FapiInteractionIdFilter

Tracks the interaction ID of requests, according to the Financial-grade API (FAPI) WG, as follows:

  • If a FAPI header is provided in a client request, includes the interaction ID in the x-fapi-interaction-id property of the response header.

  • If a FAPI header is not provided in the request, includes a new Universally Unique Identifier (UUID) in the x-fapi-interaction-id property of the response header.

  • Adds the value of x-fapi-interaction-id to the log.
