Hi,

I have read that the docs about login using registered users in firebase.

But I have already created a NoCode webapp in which I also manage my users.

I now want to create a simple barcode scanner app in Thunkable X. Users needs to login using the credentials of the webapp I created. I am thinking about sending a back a a session token to store locally.

After login a user should be able to scan de barcode. This barcode is linked to and endpoint in the webapp the is giving a JSON response with specific details.

Then the Thunkable X app should display/render these details on a new screen in the app.

Questions:

1. Is it possible use my webapp for authentication instead of firebase?
2. Is my use case possible in Thunkable X?

Thanks!

yes! use the “Web API” Component to comunicate with your webapp!
