Over the controller write your code and just return response in the "TResponse" class which has the T type Data so can return any type of data from the controller. and including with the data you can return response message and response code so that the API receiver can understand the response very well.

like this
[HttpGet]
    [Route("api/SendResponseController")]
    public TResponse SendResponseController()
    {
            var result = "My Result";
            TResponse response = new TResponse();

            //Write your code here
            //get your response in result variable and pass it your Data property
            response.Data = result;
            response.ResponseCode = 200;
            response.ResponseMessage = "Success";
            return response;

    }
and Receive like this
[HttpPost]
      [Route("api/GetInRequestController")]
      public TResponse GetInRequestController([FromBody]string request)
      {

          TResponse response = new TResponse();

          var result = request;
          //In 'request' Parameter get your requested parameter
          //do whatever want to do with this
          //return response again like this

          response.Data = null;
          response.ResponseCode = 200;
          response.ResponseMessage = "Success";
          return response;

      }

you are violating the Http stateless principle but for per user scenario you can use below code
HttpContext.Current.Items["ModuleInfo"] = "Custom Module Info"

And retrieve it like:


string contextData = (string)(HttpContext.Current.Items["ModuleInfo"]);

I think it's not good programming to passing a variable from one API controller to another API controller. I suggest you to, return that variable from apicontroller1 and then take that variable as a request in apicontroller2.
