​
Overview

This endpoint initiates a cancellation request (camt.056) message to the beneficiary system for outbound SEPA CT/Instant payments.

​
How It Works

  • Payment not yet in clearing (Created, To sign): Changes the payment status directly to Cancelled
  • Payment already sent (Sent to clear, Accepted): Sends a camt.056 cancellation request message to the beneficiary’s system
The beneficiary’s bank decides whether to accept or reject the cancellation request based on the payment status at their end.
