Customer Portal lets your customers manage their Subscription and billing information themselves. Chargebee supports Single Sign-on (SSO) to access the customer portal.
If you already have your own authentication mechanism in your app / website, Single-Sign-On allows your authenticated users to directly access portal without logging in again.
Chargebee & your application can act seamless, as one single application.
To implement Single Sign-On pass this API documentation to your developer and do not hesitate to reach out to us for any queries.
