I have a database of usernames and passwords using Firebase. I am trying to check this database from a form on my webflow website. If the username and password combination are in the database on Firebase, they can continue to the specified URL.
I have a username input field and a password input field. I need to check if these are correct (using firebase) and then send them to a URL. I know it has something to do with the "action" and the GET method, I just don't know exactly what to do.
