Handle Responses

When you process a payment using

unifiedPayment.complete()

in

Unified Checkout

, you must handle both successful responses and various errors. After the payment is complete, the

completeResponse

object contains information about the transaction outcome.

When a payment is processed successfully, you must parse the response to confirm the payment status, update their order records, and trigger any post-payment workflows. Post-payment workflows include sending confirmation emails or updating inventory. See JavaScript Example: Processing a Payment.

Your error handling should account for specific cases such as

COMPLETE_TRANSACTION_CANCELED

which is returned when the user cancels the transaction.

For PPRO-enabled online bank transfers, only cancellation errors are returned. For information about possible errors that can occur when calling the complete API see Class: AcceptError.
