Paypal express-checkout with option useraction=commit not creating transaction

I have integrated paypal express-checkout in a website. All seems to work fine. When customer is redirected to paypal for payment, the button Pay Now appears, since I am using:useraction=commit, i.e.:

https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=MYTOKEN&useraction=commit

Customer logs in from Paypal and clicks on the Pay Now button. Paypal gives no error, everything seems to be successful and customer is redirected at the RETURNURL, but no transaction is created in the buyer or in the seller account.

Solution

  • I'm afraid I missed some points from Paypal API documentation.useraction=commit will NOT complete the transaction. After returning from Paypal, we still need to execute DoExpressCheckoutPayment in order to complete the transaction.
