I’m running a twitter application which manages followers on behalf of an user. So far everything works. The users authorizes my app to do everything it needs to do and the system runs smoothly. But after a while (sometimes 1 week, sometimes 2 or more) the user access tokens expire and I get the dreaded " [89 - Invalid or expired token]". I’m careful not to run into limits and I’m not spamming. At least I’m not getting any message from twitter in this regard, which should pop up in my or the users account.
Has someone any idea why the tokens get expired after a seemingly random timeframe?
I’d greatly appreciate any nudge in the right direction. Thanks.
