TimeoutCallback

📘

Pre-Authorization Only

This method is only relevant for transactions with Pre-Authorization.

The TimeoutCallback API call notifies that the payment session has timed out due to inactivity or failure to complete the expected flow within a defined period. This callback is typically triggered when the user does not proceed with the session after a pre-authorization and no further actions, such as CancelTransactionor Settlement are received.

It serves as a final indication that the session should be considered terminated.

🚧

Timed-out Session

Do not attempt any further actions for the timed-out session. Use the SparkTransactionId to reconcile or log the timeout event.
