Error handling with paypal express checkout

[tarunks]

Is there any documentation available on zuora's knowledge centre which explains how does error handling works for paypal express checkout as payment gateway?

@tarunks,

Here is a document about PayPal Express Checkout gateway.

http://knowledgecenter.zuora.com/CB_Billing/M_Payment_Gateways/Supported_Payment_Gateways/PayPal_Exp...

As a background information, Zuora gateway integration is working like a messenger which means, Zuora sends the payment transaction API call to payment gateway and reply the gateway's response to merchant via UI or API (Depends on how the payment was created). The gateway's response contains the error codes, error messages and some other information. However, those information are basically from gateway side and Zuora does not change those information.

If you got any error while doing payments in Zuora, you can refer to PayPal Express Checkout document for the reason of failure.
