How to build token based authentication?

Hello everyone,

Softr is looking really promising for my use case but I seem to be facing a challenge.

I have a working backend where users are authenticated via a REST API, user provides email and password and receives a token in exchange to use in subsequent API calls.

How can I replicate this in Softr? It seems there is an option to add as a data source a REST API.

Thank you for the help!
