Payment API Notification
Notification is sent in case of asynchronous flow (3D Secure confirmation by the customer) - when the transaction status has changed to it's final status, usually it's confirmation, cancellation or timeout.
The asynchronous flow can be recognized by the transaction status received in response - pending_async.
{danger.fa-exclamation} IMPORTANT #1: In case if your API response contains
"status":-1or responds in unrecognized format, the notification will be resent automatically within approximately 5 minutes.
{danger.fa-exclamation} IMPORTANT #2: It is important to always pay attention at
charge_amount. Sometimes the amount processed differs fromamountdue to conversion rate (especially for crypto currencies) or fees applied.
{danger.fa-exclamation} IMPORTANT #3: Sometimes
transaction_id(PSP transaction identifier) is empty, this may happen in the cases when the PSP has rejected the processing attempt due to input validation or payment service unavailability.
