Partial Transaction Callback

Notifications sent to the address or addresses defined in the Payment Settings > Callback page of the Paywall panel for the conditions you have configured

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

Example: If in a 10-part split payment, 9 payments are successful and 1 fails, and AutoRollback is true, the 9 successful payments are canceled After all operations are completed, the system sends the payment statuses to the specified Callback address
