Hi,

I am looking on how to implement a CallBack Handler to a Web API Controller. I basically need to process the response send back by my external client.

I basically want to call the WebAPI controller from my portal so that I can place/initiate a Request to my external client. Once this client does the required actions at their end, they will need to send a CallBack so that I can process the response.

Appreciate a feedback on the above.

Regards

    Hi @Yihui Sun-MSFT ,

    In your opinion, which would be a best approach Func<...>, Action<...>, or Expression<...>?

    Appreciate if you can point to me to an example to have an idea.

    Hi @Yihui Sun-MSFT ,

    Thanks for getting back. Yes you are correct we are using Web API (Client B) as the Service Layer. However the Call from A (Web Portal) to B is through client side ($.Ajax).

    The External Client (C) is a public enitity which we are integrating with through their SDK i.e. Call from B to C is from the WebAPI through the external client's SDK. So we are not using HttpClient to send request between Client B & Client C.

    So the whole idea is for the Client C to have a Callback to Client B (Web API) in order to provide with the Response once they are done.

    Thanks.
