Facebook PHP SDK 4.0 : Getting Long Term Access Token
问题 I'm trying to use the PHP sdk v4.0 to get a long term access token for PAGE management. I'm grabbing the access token from the user's login (Yes, I'm grabbing the Page-specific access token). Then sending it to the endpoint as specified in documentation, but I'm not getting any results and I'm not getting any errors. Could I know what is the correct code snippet to use? This is the code I'm using so far $endpoint = '/oauth/access_token?'; $endpoint .= 'grant_type=fb_exchange_token&';
