Most of the TFNRegistry Application Program Interface (API) calls can take an extra parameter named "asyncId". When the user makes a call and provides a "asyncId" value, the TFNRegistry will respond with a unique Message ID as part of the same request. The Message ID provided can be used by the caller to correlate the response received on the callback URL provided, after the TFNRegistry completes processing the request. The following callback URL should be made available by the user to send the response: https://resporg-host:port/async/callback
The Responsible Organization (Resp Org) should be a valid host name (e.g.: tfnr-async.somos.com) and the allowed port value is 443 and only SSL/TLS protocol is supported for added security. For more information on how to establish this with Somos, please refer to the "Help Desk Guidelines and Practices" document in the "Find Documents" section on the Somos Portal Website (portal.somos.com).
