I would like to develop a public app which allows users to save preferences along with an email address to receive targeted information regularly.
I understand you have noted many times that Retool is intended for internal apps. But I am puzzled by the documentation on custom API authentication.
https://docs.retool.com/docs/custom-api-authentication
It seems that I could store user profiles in a separate database which requires authentication via an API - and then add custom API authentication to a public app.
Will this work?
