Hi,
today the authentication via Retool Embed suddely stopped working in our app. After some digging I discovered that if I just replaced the Retool API token with freshly created one it started to work again. Therefore I'm guessing, that the Retool API tokens have limited time of validity. It would be good to display this in the UI, so users are aware of it and can take action on it.
All the best,
Honza B.
