I have a website that takes care of getting a Facebook token through Graph / OAuth. At that point, the website can post to the user’s Facebook wall with no problems.
Is it possible to send this token to another website so the remote website can start posting the user’s Facebook wall without re-logging in the user?
Access tokens are granted per APP ID, not per domain
That being said, unless your access token includes the
offline_accesspermission, access tokens are bound to the current session so even if you managed to “pass” it to another domain, it wouldn’t work if the user was logged out (of Facebook).So, yes it should be possible under the right circumstances.
