Receiver FI Incoming Response to Request for Information (TCH)

The main Receiver FI Incoming Response to Request for Information flow.

Use case summary

The Response to Request for Information is an optional response that is initiated by a client or a client's financial institution (FI) to provide the information that was requested in a previous Request for Information transaction. It is delivered by the client's (FI) to the clearing and settlement mechanism (CSM). The CSM delivers the request to the receiver FI, who can pass the request to their client.

The sending FI may time out if it hasn’t received an acknowledgment for a request from the CSM within its time out limit. If this occurs, the sending FI resends the request to the CSM with a possible duplicate flag set. When the CSM has no record of this request, it sends it to the receiver FI as a possible duplicate. If the request is not known to the receiver FI either, it is processed normally. Otherwise, the acknowledgment for the original request is sent a second time.

The receiver FI incoming Response to Request for Information case consists of the following processing steps:
  • FTM for Immediate Payments receives a request from the CSM.
  • The request is validated, checked for duplicates, and correlated to the outgoing Request for Information and the original payment.
  • If the request has already been received by the FI and the possible duplicate flag is set, the acknowledgment for the original request is sent to the CSM again and the process completes.
  • If the previous validation step is successful, a notification is sent to the channels interface, which in turn may provide a notification to the receiver client.
  • FTM for Immediate Payments sends an acknowledgment to the CSM to confirm the acceptance or rejection of the request.
