How to validate the login of a user for the website using Chargebee's login credentials?

Problem Statement

You want to know how to validate the login of a user for the website using chargebee's login credentials.

Solution

This is indeed possible. Chargebee allows you to integrate your custom self-service portal by building user authentication on top of Chargebee. If you would want to allow access to parts of your website only to subscribers (like a paywall), you can integrate Chargebee's authentication without having to handle it from your end.

When customers are led to your custom self-service portal from your website, redirect them to the Login URL The following parameters should be passed along with the Login URL:

• return_url - The URL that users should be redirected to upon successful authentication.
• cancel_url - The URL that users should be redirected to when they want to go back to your website during login.

The domain name used in the Return/Cancel URL should be added as a 'Allow-list Domain' in Chargebee. Add just the domain name in Chargebee and not the entire URL: E.g. yourdomain.com.

Upon successful authentication, a portal session is created for the user and Chargebee redirects the user to the return_url along with the following parameters:

• auth_session_id - Identifier to the authenticated session.
• auth_session_token - Token for the session which should be sent later to activate this session.

With the auth_session_id & auth_session_token parameters, using Activate a Portal Session API, validate the session details and create a session for that user in your website.
