Hi Anthony,
Unfortunately there is not a way to prevent the token from expiring. Due to restrictions with the Facebook API, we cannot get tokens that last longer than 60 days. You can click the “Refresh your connection to Facebook” button under Events > Settings > APIsĀ before the token expires, which will at least prevent imports from being halted due to an expired token, but you will still need to log in.
I’m sorry I don’t have a better answer for you on this, but please let me know if you have any questions!
Thanks,
Jennifer
