PayPal Express Checkout Transaction Processing

 Verifying the status of a transaction programatically. To check the initial status of a

transaction, use any of the following API operations:

– DoExpressCheckoutPayment

– DoReferenceTransaction

– DoAuthorization

– DoReauthorization

You can check the subsequent status of a transaction programatically by calling the

GetTransactionDetails API operation. For more information, refer to “GetTransactionDetails

API” on page 63.

N OTE: You must use version 58.0 (or +) of the API to obtain the initial status information

provided by DoExpressCheckoutPayment, DoReferenceTransaction, DoAuthorization,

or DoReauthorization.

To use payment review with DoExpressCheckoutPayment, DoReferenceTransaction,

DoAuthorization, and DoReauthorization Payment API operations, you must

1. Check the payment status in the response to the API operation; specifically, check whether

PaymentStatus is set to Pending.

2. If the

PaymentStatus is set to Pending, check whether the PendingReason is set to

PaymentReview, because there are other reasons that a transaction may become pending.

For example, an unsettled authorization’s

PaymentStatus is set to Pending; however, its

PendingReason is set to authorization, which is not related to payment review.

PaymentStatus is set to Pending and the PendingReason is set to PaymentReview,

you should not ship merchandise or, in the case of electronic media, you should not allow

download access.

Because the payment status will change after review, you must periodically check the payment

status using the GetTransactionDetails API operation, checking email from PayPal, reviewing

IPN messages, or checking the Transaction History on
