Could anyone please assist me on how to call an external web service using OAUTH. Could you please show me the base template class I would use. I am given the following instructions on Envisionme. I already have an app on their side with the client_id and client_secret. Im just so frustrated becasue I have been searching documentation for the past two weeks and cant seem to get something to assist me :(. I wanna be able to then have a button on my contact page which will then call the class which will make the callout to that API and retrieve the response.
From what I have heard
Integration is the process which involves authentication. In general ways we use Oath2.0. Steps: 1. We need to get code (authentication code ) from external application 2. Using this code we need to get access token 3. Now you are all set to hit any external api
What I need to know then is how to implement this. Could someone please give me a sample code which I could use to authenticate and start making my posts and gets. Such as the way I would using Ready API
