I have to get an answer from an external web service that contains a json, this answer has to reach my web service, let's say https://ejemplo/json
and since I'm new using web service I do not know how to do this, my idea is that I come the json to that address and save it for me to manipulate it as necessary, but I'm lost at this point.
So far I have created webservice that receive a request and send a response, here what I try to do is just receive a json to my web service and I save it, but it is no longer necessary to send a response.
