brightback

Brightback (now Chargebee Retention) is a churn-prevention and cancellation- experience platform for subscription businesses. When a customer clicks "cancel," Brightback intercepts the flow with a personalized, hosted save experience — targeted offers, surveys, and deflection paths — driven by customer and billing context passed from the merchant. Founded as a standalone SaaS backed by Point Nine and other investors, Brightback was acquired by Chargebee in 2021 and operates as Chargebee Retention. Developers integrate via the brightbackjs client library or a server-side pre-cancel API that returns a unique Cancel Session URL, with HMAC-SHA-512 signed requests for backend calls.

brightback publishes 1 API on the APIs.io network: Retention API. Tagged areas include Company, Churn Prevention, Customer Retention, Subscriptions, and Cancellation.

brightback’s developer surface includes documentation, API reference, support, authentication, and 14 more developer resources.
