About PayPal
PayPal is one of the most popular online payment options worldwide, and it is also the most popular payment method among X-Cart's customers.
X-Cart software is pre-integrated with PayPal, so any X-Cart store can be easily set up to accept payments through PayPal. X-Cart supports both Standard and Pro PayPal solutions. More information on the PayPal solutions supported by X-Cart is available in the section PayPal Integration Overview.
Instructions on how to begin using PayPal as a payment method in an X-Cart store are available in the section Putting PayPal to Work with X-Cart.
The basics of PayPal integration testing are provided in the section Testing PayPal Integration.
Information about using the Order details page of orders paid through PayPal is available in the section Working with Orders Paid through PayPal.
PayPal Integration Overview
X-Cart supports the following PayPal solutions:
Website Payments Standard
Website Payments Standard is a simple PayPal solution available to merchants worldwide. It provides a payment method that allows your customers to shop on your website and to checkout on PayPal. In a store using Website Payments Standard, customers going to checkout see PayPal as one of the payment methods available for the order. A customer who submits an order selecting PayPal as a payment method is redirected to PayPal website. There he or she can log in to an existing PayPal account and pay using that account, or choose to pay without logging in - simply by providing the details of a credit card or a bank account. Returning to your store website from PayPal, the customer sees a confirmation page. The process of checking out through Website Payments Standard is presented in the scheme below:
Website Payments Pro
Website Payments Pro is an advanced solution composed of two payment capabilities: credit card processing with Direct Payment and PayPal payment processing with Express Checkout.
Direct Payment is a method that allows your customers to pay you with a credit card without leaving your store website. A customer enters his or her credit card information on your site, and the payment is processed in the background with PayPal's Direct Payment API. Data exchange between X-Cart and PayPal server happens transparently to the user. The customer stays on your website throughout the entire process of checkout.
Express Checkout is a fast and convenient method offering a "wallet" capability: your customer uses the billing information stored in his or her PayPal account and does not have to enter payment details or shipping information on your site. Because all the information required for order placement is taken from the customer's PayPal account, the customer may freely skip the step of logging in/getting registered at the store and complete the checkout process anonymously. When using Express Checkout, the customer is redirected to PayPal website. There, the customer logs in or signs up for a new account, selects a funding source and confirms contact and shipping information. Customer information is then passed from the customer's PayPal account to the store and is used to complete the checkout process.
The scheme below demonstrates how checkout happens with Direct Payment and Express Checkout methods:
In an X-Cart store using Website Payments Pro solution, Direct Payment and Express Checkout are provided to customers as two alternative PayPal payment options. The customers themselves choose, which of the two options they wish to use.
X-Cart's implementation of Website Payments Pro is officially PayPal Certified since X-Cart version 4.1.7.
Express Checkout
Merchants who do not wish to process credit cards through PayPal, but would still like to make PayPal available to their customers as a payment option, have the ability to use Express Checkout separately (without Direct Payment). We refer to this option as 'Express Checkout as an additional payment option', or, simply, 'Express Checkout standalone'. To be able to use Express Checkout as an additional payment option, you should sign up for PayPal's Website Payments Pro solution without submitting the Website Payments Pro application; in X-Cart, you should select the option ' Express Checkout' on the PayPal configuration page.
Unlike Website Payments Pro, Express Checkout standalone is not limited to the US and Canada.
Website Payments Pro Payflow Edition
In addition to Website Payments Pro, X-Cart provides support for another PayPal's solution - Website Payments Pro Payflow Edition. If you are from the US or UK and are interested in using this solution, you should discuss the possibility with a US or UK sales representative or account manager from PayPal.

PayPal Integration Overview
X-Cart integrates with three types of payment solutions by PayPal:
- All-in-One Payment Solutions (PayPal Payments Standard, PayPal Payments Advanced, PayPal Payments Pro)
- Payment gateways (Payflow Link, Payflow Pro)
- Alternative Methods of Payment (PayPal Express Checkout)
For more information on each type of payment solutions, see Understanding Online Payments.
All-in-One Payment Solutions
The following are PayPal solutions that give you an Internet merchant account and payment gateway in one solution.
PayPal Payments Standard
(also known as Website Payments Standard outside the U.S.)
PayPal Payments Standard is a simple all-in-one PayPal solution that allows you to accept credit card and PayPal payments securely. Your customers shop on your website and checkout on PayPal. The process is as follows: Customers who select PayPal as a payment method are redirected to PayPal website. There they can log in to an existing PayPal account and pay using that account, or choose to pay without logging in - simply by providing the details of a credit card or a bank account. Then such customers return to your store site where they see a confirmation page. The process of checking out through PayPal Payments Standard is presented in the scheme below:
More information about PayPal Payments Standard is available here and here.
PayPal Payments Advanced
PayPal Payments Advanced is an all-in-one PayPal solution that enables you to keep customers on your site for the entire checkout process without the full burden of protecting their financial data. With this solution you get a secure checkout template from PayPal that is integrated within your website and allows your customers to enter their payment information on PayPal without actually leaving the store website. Your customers won't even know that PayPal is processing their payment, making your business look more secure and professional. With PayPal Payments Advanced, PCI DSS compliance is made easy for you because payments are handled not by your site directly, but by PayPal.
More information about PayPal Payments Advanced is available here.
PayPal Payments Pro
(also known as Website Payments Pro outside the U.S.)
PayPal Payments Pro is an all-in-one solution available in two versions:
- PayPal Payments Pro (Direct Payment)
- PayPal Payments Pro (Payflow Edition)
Each of the versions provides two payment capabilities:
- Credit and debit card payment;
- PayPal payment with Express Checkout.
With PayPal Payments Pro (Direct Payment) credit and debit card processing is done via PayPal's Direct Payment API (PayPal API), with PayPal Payments Pro (Payflow Edition) - via PayPal's Payflow API.
Below is more information about the PayPal Payments Pro payment capabilities:
With PayPal Payments Pro, customers can pay you with a credit or debit card without leaving your store's website. Customers enter their payment information on your website, and the payment is processed in the background with PayPal. This way customers stay on your website throughout the entire process of checkout.
You must understand that using Direct Payment involves your X-Cart store in handling and transferring credit card data to the payment gateway (PayPal). As per PCI DSS requirements, this can be done only by a PA-DSS validated application. Unfortunately, X-Cart is not such an application. To enable you to meet PCI DSS requirements, we offer a special PA-DSS validated application - X-Payments. It is a kind of "bridge" between your X-Cart store and the payment gateway (PayPal), which handles all credit card data supplied by the buyer, and transfers the sensitive data securely to the payment gateway (PayPal).
Express Checkout is a fast and convenient method offering a "wallet" capability: your customers use the billing information stored in their PayPal accounts and do not have to enter their payment details or shipping information on your site. Because all the information required for order placement is pulled from PayPal, your customers may freely skip the step of logging in/getting registered at your store and complete the checkout process anonymously.
When using Express Checkout, customers are redirected to PayPal website. There they can choose one of the two options:
- Log in and pay using their existing PayPal account info.
- Pay with their debit or credit card as a PayPal guest, entering the payment info directly at PayPal side.
Customer information is then passed from PayPal to the store and is used to complete the checkout process.
With Express Checkout, all cardholder data processing is outsourced to and handled by PayPal, so from the viewpoint of handling and transferring credit card data your X-Cart store is PCI DSS compliant.
The graphic scheme below demonstrates how credit/debit card payments and PayPal payments via Express Checkout are processed with PayPal Payments Pro:
More information about PayPal Payments Pro is available here.
A comparison chart for PayPal's All-in-One solutions (Standard/Advanced/Pro) is available here.
Website Payments Pro Hosted Solution
Website Payments Pro Hosted is an all-in-one PayPal solution that allows you to securely accept credit and debit card or PayPal payments without capturing or storing card information on your store website. Payment information is collected by PayPal through a compact payment form integrated on your website using an inline frame (iFrame). The buyer completes the payment on your website, and you can maintain the checkout look and feel in the master frame that surrounds the compact form. The credit card fields are part of the compact form so you do not have to collect this information separately, which helps achieving PCI compliance. More information is available here.
PayPal Payment Gateways
The following are PayPal solutions for merchants who wish to accept payments using their existing payment processor and Internet Merchant Account:
Payflow Link
Payflow Link payment gateway allows you to accept payments from your customers using secure, PCI compliant hosted payment pages. This solution is technically identical to PayPal Payments Advanced, except that it integrates with merchant accounts from other financial institutions. With Payflow Link, you do not have to collect cardholder data, as PayPal does that on your behalf; so you do not have to deal with the PCI compliance burden for PayPal transactions.
Payflow Pro
Payflow Pro provides a lot more flexibility allowing you to build a checkout experience as unique as your own business. With this solution, the payment form for your customers is located on your store website, which means you handle credit card payments and transmit cardholder data to the payment gateway. This, of course, imposes more stringent requirments on your environment in terms of PCI DSS compliance.
More information about PayPal's Payflow payment gateway is available here.
Alternative Methods of Payment
The following is a PayPal solution for merchants who do not wish to process credit cards through PayPal, but would still like to make PayPal available to their customers as a payment option.
PayPal Express Checkout
We refer to this option as 'Express Checkout as an additional payment option', or, simply, 'Express Checkout standalone'. It allows you to minimize the number of steps customers must complete when they checkout. Customers using Express Checkout pay on PayPal’s secure site and return to your store site to complete the transaction. This solution is designed for merchants who do not have an Internet Merchant Account for processing credit and debit card payments.
More information about PayPal Express Checkout is available here.

See how to configure Paypal methods in X-Cart
This section provides links to video instructions for setting up some PayPal payment methods in X-Cart:
Testing your PayPal payment methods
Before you make your PayPal payment methods publicly available on your store website, you may want to run some PayPal transactions in test mode to familiarize yourself with PayPal and to ensure that everything works correctly.
Testing of the PayPal Payments Advanced, Website Payments Pro Payflow Edition, Payflow Link and Payflow Pro methods is performed using the PayPal Manager - the same administration interface that you should use for live transactions.
Testing of the PayPal Payments Standard, PayPal Payments Pro, Website Payments Pro Hosted Solution and Express Checkout methods is performed using the PayPal Sandbox - a self-contained testing environment for PayPal applications. The Sandbox mirrors the features found on the PayPal production servers and allows you to run test checkouts without any money changing hands or accounts being debited.
Testing with PayPal Sandbox: PayPal Payments Standard, PayPal Payments Pro, Website Payments Pro Hosted and Express Checkout solutions
When testing with the Sandbox, follow these steps:
- Sign up for a Developer Central account at https://developer.paypal.com.
- Create a set of virtual test accounts in the Sandbox.
- Obtain correct API credentials for test mode.
- Set your PayPal payment method to work in test mode.
- Conduct test PayPal transactions.
Signing up for a Developer Central account
To be able to access the PayPal Sandbox, you need to have an account at Developer Central.
To sign up for a Developer Central account:
- Go to https://developer.paypal.com.
- Click Sign Up.
- Follow the instructions on the screen to create an account.
Creating a set of virtual test accounts in the Sandbox
The Sandbox supports two different types of test accounts: Business and Personal. Personal Sandbox accounts are used to make test payments via PayPal, Business Sandbox accounts - to accept the test payments.
To test a typical PayPal transaction, you need both a Business test account and a Personal one. When you register as a PayPal developer, the Sandbox automatically creates for you a Business test account and its associated test credentials. However, you still need to create a Personal account to act as the buyer in your mock transactions.
To create a test account in the Sandbox:
- After logging in to Developer Central at https://developer.paypal.com, navigate to Applications > Sandbox Accounts.
- Click the Create account button.
- Select the type of account that you wish to create (Business or Personal).
- Populate the rest of the account details fields.
- Click Create Account.
After creating some Sandbox test accounts, you can log in to the Sandbox as the respective test users.
To log in to the Sandbox using a specific test account:
- Log in to Developer Central and navigate to the Sandbox Account page (Applications > Sandbox Accounts).
- Select the test user that represents the feature you want to test and click the 'Sandbox site' link next to it. The Sandbox site will open in a separate window.
- Use the credentials of the chosen test user to log in to the Sandbox.
Please note the following:
- Sandbox accounts are not in any way tied to your PayPal account on www.paypal.com.
- When creating a test account in the Sandbox, your email address attached to that account does not need to be real. It can be any email address, as long as the email address does not already exist on the Sandbox.
- Email from the Sandbox will never be delivered to the email address you enter. All email generated by the Sandbox is captured and displayed by the Developer Central email client.
- After creating a Sandbox account, you may want to confirm the email address for the sandbox user. Check the email client on Developer Central to confirm your email address.
- After creating a Sandbox account, you can also attach a test credit card and bank account for testing.
- More information about the Sandbox is available in the "Testing Classic API Calls" guide:
https://developer.paypal.com/webapps/developer/docs/classic/lifecycle/ug_sandbox/
Getting your test API credentials
All PayPal API requests require API credentials to verify the call is being made through a valid PayPal account. Calls to the Sandbox environment are no different, but they require that you use the test credentials assigned to one of your Business test accounts.
Important: The PayPal Sandbox and production environments each use different sets of API credentials. Be sure to use the correct set of credentials.
To obtain your test API credentials, sign in to the Sandbox using your seller test account and follow the instructions for obtaining API credentials (See "How do I get my API credentials? > On the Sandbox" at http://qwyx.co/apihowto).
Setting your PayPal payment methods to work in test mode
To set your PayPal payment method to work in test mode:

- In the Test/Live mode field, select 'Test'.
- Make sure the rest of the fields are adjusted the way you are going to use them in Live mode.
- Click Save to save the changes.
- In your X-Cart store's Admin area, go to the PayPal configuration page.

- Click Update to save the changes.
When you return to the list of your store's payment methods after setting PayPal to work in test mode as described above, there should be a warning message below the 'PayPal' entry:
This is normal when X-Cart's PayPal integration is in test mode. Now you can perform test PayPal transactions.
Conducting test PayPal transactions
The test accounts that you set up in the PayPal Sandbox allow you to explore how PayPal works for merchants and customers. To find out about the merchant's side of the matter, you need to log in to the Sandbox as a user of the 'Business' type. To make test PayPal payments and to learn about the customer's side of the matter, you need to log in to the Sandbox using a 'Personal' account.
Important: In the test mode, to pay for an order using a PayPal payment method, you need to be logged in to Developer Central. Developer Central sessions time out quickly, so it is recommended you log in to Developer Central shortly before going to checkout. The recommended method for logging in to Developer Central is to open a new window in the web browser being used for viewing the store directly before you click the Checkout button on the Shopping cart page and to use that window for logging in to Developer Central. Please note that, if you happen to go to checkout without previously logging in to Developer Central, or if your Developer Central session expires by the time you begin checking out, you will be able to complete checkout, but the process will be a little less streamlined (After selecting PayPal as a payment method and clicking the Submit order button, you will be offered to log in to Developer Central. After logging in, you will be required to click the Back button of your web browser several times to return to the store's 'Place order' page. There you will need to click the Submit order button again to resume the checkout process.)
Testing with PayPal Manager: PayPal Payments Advanced, Website Payments Pro Payflow Edition, Payflow Link and Payflow Pro solutions
To test PayPal Payments Advanced, Website Payments Pro Payflow Edition solutions, Payflow Link and Payflow Pro, follow these steps:
- Obtain API credentials for testing.
- Set your PayPal payment method to work in test mode.
- Conduct test PayPal transactions.
Obtaining API credentials for testing
To be able to test PayPal using the PayPal Manager, you need a regular Payflow account.
If you do not yet have such an account, start the sign-up process and proceed to provide all details, including the "login details". Once you get to the billing section, simply cancel out of the registration process by closing the tab. You will have a Payflow account in a 'test' state at this point.
If you have already completed the registration process earlier, you can check the current status of your account in the 'Your Account Status' section on the PayPal Manager Home page. This section indicates if your status is Test or Live. To run test transactions, you need to switch to 'Test'.
Your API credentials for testing are as follows:
- Partner: PayPal
- Merchant login: The merchant login you created during the registration process.
- Password: The merchant password you created during the registration process.
- User: Empty.
Alternatively, if you want to create a dedicated user to use for the API's, you can log on to https://manager.paypal.com with the credentials and go to 'User settings', and create a secondary user. The username for this user would need to be entered in 'User', as well as the password of the user in 'Password'.
It may take up to an hour before new credentials become active.

After setting your account status to 'Test', you can run mock or test transactions to familiarize yourself with PayPal Manager and make sure your account is set up correctly. When you run test transactions, they are not sent to financial institutions for processing, and no money trades hands.
Once you have completed testing your transactions, you will want to change to Live status by clicking the Activate Your Account button on the PayPal Manager Home page; also be sure to switch to 'Live' mode on the PayPal configuration page for your particular product in X-Payments/X-Cart.
Make sure you have an internet merchant account before you activate your account; otherwise, your live transactions will fail.
Working with Orders Placed through PayPal
Obtaining information about orders placed through PayPal
Orders that your customers place selecting PayPal as a payment method are accumulated in the 'Orders Management' section of your store, along with all other orders.
The current status of an order placed through PayPal appears in the 'STATUS' box pertaining to that order - the same way as for orders paid by other methods.
Detailed information is available on the 'Order details' page. Information about the payment transaction(s) pertaining to the order appears on the 'Order details' page as follows:
- 'Order info' section of the 'Order details' dialog box: Name of the payment method used, order amount.
- 'Order details (not visible to customer and provider)' section of the 'Order details' dialog box: Advanced info about the transaction by which the customer paid for the order (as received from PayPal and interpreted by X-Cart's PayPal payment module).
- 'PayPal transactions' dialog box (not available for orders paid using PayPal Payments Standard):
'Original transaction' section - Comprehensive information about the transaction by which the customer paid for the order.
'Refund transactions' section - Information about the refund transaction (or a series of partial refund transactions) by which the original payment was refunded. Is displayed only if the original transaction was refunded by the store administrator.
Understanding the statuses of orders placed through PayPal
As orders placed through PayPal are processed, they receive statuses according to the scheme used by X-Cart (see X-Cart:Orders#Order_Statuses article). The statuses that you can see in the 'STATUS' boxes of PayPal orders are Not finished, Queued, Pre-Authorized, Processed and Failed. These statuses are assigned to orders automatically based on the statuses of the respective payment transactions on PayPal:
When a customer places an order using PayPal as a payment method, the order is created with the status Not finished.
Sometimes it happens that a transaction cannot be processed by PayPal immediately; in this case, PayPal temporarily sets the status of the order to 'Pending'. In X-Cart, PayPal's 'Pending' status corresponds to Queued.
If your store is configured to use PayPal in 'Auth and Capture' mode, the status that follows Not finished or Queued is either Processed or Failed. The status Processed corresponds to the state 'The payment has been successfully processed by PayPal; the customer's card has been charged'. The status Failed corresponds to the state 'The transaction has been declined by PayPal'.
If your store is configured to use PayPal in 'Auth only' mode, the status that follows Not finished or Queued is either Pre-Authorized or Failed. The status Pre-Authorized corresponds to the state 'The payment has been successfully authorized'. The status Failed corresponds to the state 'The payment has been declined by PayPal'.
After the order's status is set to Pre-Authorized, you can either capture the authorized amount or void the transaction. If you choose to perform the 'capture' operation, you use the Capture button; after the authorized amount is captured, the status of the order is set to Processed. If you choose to perform the 'void' operation, you use the Decline button; after the authorization is voided, the status of the order changes to Declined.
Assigning any other statuses to PayPal orders has to be done manually by re-adjusting the value of the 'STATUS' box. For example, if an order successfully processed by PayPal and completed by the store needs to be marked as such, you will have to select Complete from the 'STATUS' box of the respective order and update the status.
Updating information about the transaction by which the customer paid for the order
For orders paid through PayPal Payments Pro, Website Payments Pro Payflow Edition or Express Checkout, detailed information about the transaction by which the customer paid for the order is displayed in the 'Paypal transactions' dialog box in the 'Orders Management' section (See the 'Original transaction' subsection). You can obtain the latest available information about this transaction at any time: simply click the Update button in the 'Original transaction' section. X-Cart will submit your request to PayPal server and the information in the 'Original transaction' section will be updated.
Issuing refunds
X-Cart allows you to issue refunds for orders paid through PayPal Payments Pro, Website Payments Pro Payflow Edition and Express Checkout.
Orders paid for using PayPal Payments Pro or Express Checkout can be refunded either at once (by issuing a single refund transaction for the entire sum of the original transaction) or in portions (by issuing several partial refund transactions one after another). If you choose to do a refund as a series of partial refund transactions, you will have to specify the amount for each of the partial refund transactions separately.
Orders paid for using Website Payments Pro Payflow Edition can be refunded only by issuing a refund for the entire sum of the original transaction at once.
To issue a refund:
- Open the 'Order details' page of the order that needs to be refunded.
- Scroll down to the 'PayPal transactions' dialog box.
- Use the 'Issue refund' section of the 'PayPal transactions' dialog box to create a refund:
- In the 'Amount' field, enter the amount to be refunded (Available only for PayPal Payments Pro. For Website Payments Pro Payflow Edition, the refund amount is already specified, and it equals the order amount).
- In the 'Note' field, provide a note stating the reason of the refund.
- Click the Create button.
As soon as the refund request is successfully received and processed by PayPal, the refund transaction appears in the 'Refund transactions' section of the 'PayPal transactions' dialog box. For each refund transaction, the following information is available:
- TRANSACTION ID - Transaction ID;
- AMOUNT - Refund amount;
- DATE - Date when the transaction was performed;
- NOTE - Note with which the refund was issued.
Troubleshooting
Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address
Such error message appears on the PayPal checkout page when customer's address does not pass PayPal's validation.
A valid address is specified by customer when checking out using X-Cart. The address is used for the calculation of shipping and tax charges before customer proceeds to PayPal's payment page. When customer submits an order to be paid with PayPal, the customer's address is passed from X-Cart to PayPal along with the other payment details.
If the customer's address submitted to the server does not pass PayPal's validation, the server returns the error specified in the question title. To fix it and continue with the payment, the customer should go back to the store, correct the address and submit the order again.
Please note that the customer's address submitted from X-Cart to PayPal overrides the PayPal member's stored address. The customer can see the submitted address but cannot edit it.
There is also another way to eliminate the error. You can allow your customers to edit the submitted address or select a different address that the customer has on his or her PayPal account. To do so, please make the following changes in <xcart-dir>/payment/ps_paypal.php:
Find the line:
"address_override" => 1,and replace it with this one:
"address_override" => 0,
We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller
The most probable cause of the problem is invalid data that you might have entered in the Account field on the Paypal settings page in the X-Cart admin area. For the 'PayPal Payments Standard' method, this field should contain your PayPal account's email address.
Please correct the Paypal settings according to this article:
If this does not help to resolve the problem, feel free to contact the X-Cart support team.
Telephone number not showing with Paypal Express
PayPal has a setting that will display and validate a customer contact phone number field on the payment page. PayPal recommends leaving this feature "Off" because customers value their privacy. Thus this option is off by default.
You can set up your PayPal account's preferences to require the phone number to be supplied when customers are making a purchase. In your PayPal account, click on Profile, then Website Payment Preferences, then enable the option under Contact telephone number.
For more information, see the section "Obtaining the Buyer’s Telephone Number During Checkout" in https://www.paypalobjects.com/webstatic/en_US/developer/docs/pdf/pfp_expresscheckout_pp.pdf
This invoice has already been paid. For more information, please contact the merchant
Problem description:
When our client checkout to pay us at PayPal this message came up after they press on submit order:
This invoice has already been paid. For more information, please contact the merchant.
Solution:
Usually such error occurs when the same PayPal account is used for more than one on-line stores.
To get rid of the error, change the "Order prefix" value on the PayPal configuration page for all your X-Cart stores. Make sure the order prefix value is unique for each on-line store.
The same solution should be applied when using PayPal Pro and getting this error:
Reason: Declined Status: Error: Payment has already been made for this InvoiceID. (Code: 10412, Severity: )
Orders in multi-vendor X-Cart stores /Orders with large product quantities/large total amount not getting processed properly
Orders with large quantities of ordered products and/or large total amount, as well as orders created in a multi-vendor store and containing products of more than one vendor (provider), may get the status "not finished" in the X-Cart store's back end (instead of "processed") - regardless of the fact that the payment has been processed ok by PayPal. In most cases this problem is related to the operation of Paypal Fraud Protection Services. The reason for orders not getting processed properly in this case is that your transactions get the status "Under Review by Fraud Service" (Result Code 126 — "Flagged for review by filters"). If you had transactions in your store that got "filtered" by PayPal Fraud Protection Services, you can view them on the Fraud Transactions Report page. To resolve the problem, it is recommended to adjust the settings of your PayPal FPS filters.
Reason: Declined: Accepted Status: Completed (TransID #xxxxxxxxxxxx); Payment amount mismatch: wrong order total ( 21.10 <> 33.10 ).
This problem may be caused by PayPal Shipping Calculator configured in your PayPal merchant profile (Profile->My Selling Tools->Shipping my items->Shipping calculations). To resolve this issue, disable the calculator according to the guidelines provided in https://www.paypal.com/webapps/mpp/get-started/shipping-calculator
Testing PayPal Integration
Before you make PayPal publicly available as a payment method on your store website, you may want to run some PayPal transactions in test mode to familiarize yourself with PayPal and to ensure that everything works correctly.
Follow these steps:
- Obtain a verified PayPal business account.
- Set your store's PayPal integration to work in test mode.
- Conduct test PayPal transactions.
Obtaining account for testing
Testing of PayPal's Website Payments Standard, Website Payments Pro and Express Checkout solutions is performed using the PayPal Sandbox - a self-contained testing environment for PayPal applications. The Sandbox is a mirror of the real PayPal site except that real financial transactions are not made. To be able to access the PayPal Sandbox, you need to have an account at Developer Central. You do not need an existing live PayPal account in order to sign up for Developer Central. After becoming a member of Developer Central, you will be able to access the Sandbox either directly or by launching it after you log in to Developer Central.
To sign up for a Developer Central account:
- Go to https://developer.paypal.com.
- Click 'Sign Up Now'.
- Follow the on-screen instructions.
After you submit the required information to PayPal, PayPal sends login instructions to the email address you used to sign up. Follow the instructions provided to you in the email message to log in to Developer Central. Now you can create the accounts required for testing.
Basically, you need accounts of two types: Business and Personal. A Personal Sandbox account is needed to make test payments via PayPal, a Business Sandbox account - to accept these payments.
Creating a test account in the Sandbox is easy:
- After logging in to Developer Central, click 'Sandbox'.
- Click the link 'Create account'.
- Select the type of account that you wish to create (Business or Personal).
- Follow the on-screen instructions to create the account.
After creating the necessary Sandbox accounts, you will be able to log in to the Sandbox as a test user of the necessary type.
To log in to the Sandbox using a specific test account:
- Log in to Developer Central.
- Click the 'Sandbox' tab.
- Select the test user that represents the feature you want to test.
- Click 'Launch Sandbox'.
Please note the following:
- Sandbox accounts are not in any way tied to your PayPal account on www.paypal.com.
- When creating a Sandbox account, your email address attached to that account does not need to be real. It can be any email address, as long as the email address does not already exist on the Sandbox.
- Email from the Sandbox will never be delivered to the email address you enter. All email generated by the Sandbox is captured and displayed by the Developer Central email client.
- After creating a Sandbox account, you may want to confirm the email address for the sandbox user. Check the email client on Developer Central to confirm your email address.
- After creating a Sandbox account, you can also attach a test credit card and bank account for testing.
- More information about the Sandbox is available in the PayPal's Sandbox User Guide (https://developer.paypal.com/en_US/pdf/PP_Sandbox_UserGuide.pdf).
Testing of PayPal's Website Payments Pro Payflow Edition solution is performed using the PayPal Manager - the same administration interface that you should use for live transactions, https://manager.paypal.com. You will be able to access this interface as soon as you set up your production merchant account.
Setting Your Store's PayPal Integration to Work in Test Mode
Your store's PayPal integration can be set to work in test mode as follows:
Website Payments Standard:
- Go to the PayPal configuration page in your store's Admin area.
- From the 'Settings' dialog box, select the desired option ('Website Payments Standard').
- Adjust the configuration fields for the selected option:
- Specify your Sandbox Business account.
- Configure the fields 'Payment for', 'Currency', 'Order prefix' as desired.
- Set PayPal operating mode to 'Test'.
- Click the Update button to save the changes.
Website Payments Pro and Express Checkout used as an additional payment option:
- Log in to your Sandbox Business account to obtain API credentials for the test mode (The Sandbox Business account backoffice is organized similarly to the backoffice of your production PayPal Business account, so API credentials for the test mode can be obtained the same way as described in the section ' Setting up Your API Access', with the difference that the Business account in the Sandbox should be used instead of the production account).
- Go to the PayPal configuration page in your store's Admin area.
- From the 'Settings' dialog box, select the desired option ('Website Payments Pro' or 'Express Checkout').
- Adjust the configuration fields for the selected option:
- Specify the API access credentials as provided by your Sandbox Business account.
- Configure the fields 'Currency' and 'Order prefix' as desired.
- Set PayPal operating mode to 'Test'.
- Click the Update button to save the changes.
Website Payments Pro Payflow Edition:
- Go to the PayPal configuration page in your store's Admin area.
- From the 'Settings' dialog box, select the desired option ('Website Payments Pro Payflow Edition').
- Adjust the configuration fields for the selected option:
- Configure the fields 'Vendor', 'Partner', 'User' and 'Password'.
- Configure the fields 'Currency' and 'Order prefix' as desired.
- Set PayPal operating mode to 'Test'.
- Click the Update button to save the changes.
When you return to the list of your store's payment methods after setting PayPal to work in test mode as described above, there should be a warning message below the 'PayPal' entry:
This is normal when X-Cart's PayPal integration is in test mode. Now you can perform test PayPal transactions.
Using PayPal in Test Mode
Website Payments Standard, Website Payments Pro and Express Checkout solutions:
The test accounts that you set up in the PayPal Sandbox allow you to explore how PayPal works for merchants and customers. To find out about the merchant's side of the matter, you need to log in to the Sandbox as a user of the 'Business' type. To make test PayPal payments and to learn about the customer's side of the matter, you need to log in to the Sandbox using a 'Personal' account.
Important: In the test mode, to pay for an order using a PayPal payment method, you need to be logged in to Developer Central. Developer Central sessions time out quickly, so it is recommended you log in to Developer Central shortly before going to checkout. The recommended method for logging in to Developer Central is to open a new window in the web browser being used for viewing the store directly before you click the Checkout button on the Shopping cart page and to use that window for logging in to Developer Central. Please note that, if you happen to go to checkout without previously logging in to Developer Central, or if your Developer Central session expires by the time you begin checking out, you will be able to complete checkout, but the process will be a little less streamlined (After selecting PayPal as a payment method and clicking the Submit order button, you will be offered to log in to Developer Central. After logging in, you will be required to click the Back button of your web browser several times to return to the store's 'Place order' page. There you will need to click the Submit order button again to resume the checkout process.)
Website Payments Pro Payflow Edition solution:
The first time you log in to PayPal Manager, you are in Test status (the Home page of PayPal Manager indicates this). This means that you can run mock or test transactions to familiarize yourself with PayPal Manager and make sure your account is set up correctly. These test transactions are not sent to financial institutions for processing, and no money trades hands.
When you are ready to run actual transactions, you will change to Active, or Live status. To change to Active status or see which status you are in, go to the Home page of PayPal Manager and look at the 'Your Account Status' section on the right side. Even after your account is active, you can still perform test transactions if necessary.
At any time, you can activate your account (change to Live status) by clicking the Activate Your Account button on the Home page.
Make sure you have an internet merchant account before you activate your PayPal services account. Otherwise, your live transactions will fail.
