The second type of invocation is asynchronous in nature and used by the external system to request the response to be sent to an external system endpoint so that the polling process can be avoided. The TFNRegistry™ API will reply to the original request started by an external system or provide any error information.
All the asynchronous responses are in JSON format and transported via HTTPS protocol.
Every external system requesting to interact with the TFNRegistry API in an asynchronous manner must:
- Expose a generic JSON over HTTPS API interface in a public URL where asynchronous responses may be sent.
- Register an endpoint URL with the TFNRegistry as part of the API request to receive asynchronous the response messages.
