Partial Transaction Callback

Callbacks sent to the address(es) defined under Payment Settings > Callback in the Paywall panel, based on the conditions you specified.

In partial payment transactions, if one or more payments fail and the AutoRollback parameter is set to true for the successful payments, a cancellation process is triggered. Once the cancellations are completed, the payment results are sent to the specified Callback address, and the final status is reported.

Example: If 9 out of 10 split payments are successful and 1 fails, and AutoRollback is set to true, the 9 successful payments will be canceled. Once all operations are completed, the system sends the payment statuses to the specified Callback address.
