For a specific customer requirement, we use Custom UI for user login, instead of universal login provided by Auth0. The idea is to:
have a custom login widget (email, password) on the home page and call Auth0 Login API (for dbconnection) using AJAX.
on successful login, get the token (JWT?) from Auth0 and pass it to the backend, which will then use this to get userprofile.
So, as part of this,I was looking for the specific login API (using email & password) under: https://auth0.com/docs/api/authentication but could not find the one to suit this need. Can you please help with the exact Auth0 API endpoint to use and the steps to invoke it.
NOTE: I was able to figure out the signup/register-user API (get access_token using client_credentials grant and then invoke https://MY-DOMAIN/dbconnections/signup with the access_token) from the documentation and it works fine, but not the sign-in/login one.
