I want to create a web app for a third party service.
The service is a loyalty program, so what I want to do is create a login/register page for users, where they can input their username and password and see their history, data, number of points, etc, and also redeem prizes online, or create a new account if they don't have one. The web app access would be just for the clients, not the backend and admin areas.
So I think what I'd have to do is connect form fields with the 3rd party API using the wix-fetch API, and then create a page where the user's information is displayed, and I would have to create a backend module to run this so my API key stays hidden, but... I'm not sure how to do this. Is it possible?
