Question

I want that everyone can send a message to a friend after the user is logged out from facebook.

So I save the access token but when I logout from facebook, then facebook tell me that the token is expired because the user is logged out.

Maybe do I have to request some particular permission ? I know that offline_access permission is deprecated… so what do I have to do ?

This is the error:

   "error": {
      "message": "Error invalidating access token: The session is invalid because the user logged out.",
      "type": "OAuthException",
      "code": 190,
      "error_subcode": 467
   }

P.s. I am using JS SDK but I think that this doesn’t matter.

You will have to extend you access token, have a look at this :

Facebook reference how to handle offline_permissions:

You should be able to manage.

@Alexandre Couturon Reference :

If you get an Access Token client-side (JS SDK) you will get a short-lived token. You can exchange this token for a long-lived one with the exchange oAuth endpoint:
