Requesting JSON response from facebook Graph API

facebook-graph-api, json

Solution

Unfortunately, this is one of the only calls in the Facebook API that does not return JSON. You can reference the still open bug on the Facebook developers site:

https://developers.facebook.com/bugs/351715371565218

I use the FB .NET SDK and retrieve the new token thusly:

newAccessToken = responseString.Split('=', '&')[1];

Problem

This might be a very simple question, but I just need to have a JSON response from Facebook for ths query https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id='my app id'&client_secret='my secret id'&fb_exchange_token='old_token' This works and returns a response with a long term Facebook token. But I just need to have the response in JSON format. How can I do that?
