In order for your Groups Access Token to never expire you must first be an admin of a Facebook “Page”. This is because Facebook Page tokens never expire by default and so we can then “exchange” the tokens to ensure that your Groups token also doesn’t expire.
If you already an admin of a Facebook Page then you’re good to go. Just use the button inside our plugin to connect your group and your token will never expire. If you are not an admin of a Facebook Page then you would need to create one first (or be made an admin on an existing page). You can simply create a blank Facebook page for this purpose. Once you are an admin of a Facebook page then simply use the button inside our plugin again and the token should then automatically be extended so that it never expires.
