API

Last updated: Apr 22nd, 11:54am

Returns from the following NVP/SOAP API calls:

CreateBillingAgreement

DoExpressCheckoutPayment

GetBillingAgreementCustomerDetails

GetExpressCheckoutDetails

SetExpressCheckout

Cause

The Express Checkout token was issued for another merchant account: The token provided in the API call does not belong to the merchant account making the request.

Invalid token: The token provided in the API call is not valid. This could be due to a typo, an expired token, or a token that does not exist.

Token already used: The token has already been used for a previous transaction. PayPal tokens are single-use.

Incorrect transaction ID: The transaction ID does not match any existing transactions or is incorrect.

Impact

The payment process is halted, preventing the customer from finalizing their purchase. This can lead to a poor customer experience and potentially lost sales if the issue is not resolved promptly.

Resolution

Check merchant account: Ensure that the token provided in the API call was issued for the merchant account making the request. Verify that you are using the correct merchant credentials.

Validate token: Ensure that the token provided in your API request is valid and not expired. Double-check for any typos or errors in the token.

6];

    Check token usage: Verify that the token has not already been used for a previous transaction. PayPal tokens are single-use.

    Verify transaction ID: Ensure that the transaction ID provided in your API request matches an existing transaction and is correct. Double-check for any typos or errors in the transaction ID.

    Review your code: Review your code to ensure that the token and transaction ID are not being changed or modified at any point before the API call.
