Question

After following the steps of the answer marked correct on this question, I was able to post to my Facebook page via my app, the problem is the access token expires after 2 hours, I have gone through so many articles and found a lot of different ways but can't get them to work, I want to be running this script every our with cron jobs so i post different articles to my page, is there no way of getting a permanent access token?

Answer 1

Create a long lived access token using a facebook application. Currently the long-lived user access_token will be valid for 60 days while the short-lived user access_tokens are currently valid from 1 to 2 hours.

You can create your own application and create a user accesstoken from it by logging in through it.
