REST API Call to Salesforce Org using Visualforce page
I'm trying to use REST APEX API that I created in a dev.Org(A). And I want to use this APEX REST Service in an another Dev Org(B) using REST call to "A" from "B". I cretaed a simple VF page with controller class and some logic inside it to call this serivce.
Everything works well till the point i get the "code" value after successful authorization of from "A". But when I try to create a request to get the token/refesh_token part i get a strange error:- error=unsupported_grant_type&error_description=grant%20type%20not%20supported.
following is the piece of code
Http h = new Http();
HttpRequest req = new HttpRequest();
req.setMethod('POST');
req.setHeader('grant_type','authorization_code');
req.setHeader('code',code);
req.setHeader('client_id',clientId );
req.setHeader('client_secret',client_secret);
req.setHeader('redirect_uri',callbackUrl );
req.setHeader('Content-Type','application/x-www-form-urlencoded');
req.setEndpoint('https://login.salesforce.com/services/oauth2/token');
HttpResponse res = null;
res = h.send(req);
system.debug('###'+res.getBody()+'#####');
This is what exaclty I did and am successfull...........
It's pretty tricky, You have to get a token for a user in the target org(dev.org A in this case). You can't do this using login.salesforce.com, since you'll likely just get a token for your source org, which won't work.
I have posted exaclty similar query and Pat helped me alot for this to happen successfully. This post gives you whole Idea and solves your issue.

Hi Vikash,
I tried the exact same code which you posted but I get an error message saying not able to get to the service. It does the authentication and the access_token is also sent back. But when I click on the submit button, its not able to find the service.
Even in the same target org, if I try to execute the getnamemethod to get the results,it says unauthorized endpoint.
can you help me on that?
Thanks,
