Getting Started with the Churn Buster API

This document outlines how to connect your subscription management tool to Churn Buster so the proper events are transferred over for accurate measurement of failed payment recovery.

To get started:

1. Payment Failures

When a recurring payment fails, notify Churn Buster to track the volume of failed payments and monitor outcomes.

2. Successful Payments

When a recurring payment succeeds, notify Churn Buster to track successful recoveries.

3. Subscription Cancellations

When a subscription is cancelled, notify Churn Buster to track lost recoveries.

4. Payment Method Updates

When a customer's default payment method is updated, notify Churn Buster. This enhances your analytics by also tracking recovery method: retry vs. card update.

Once all event types are being sent over through your Test API Keys (verified in the Test Debugger), please request a QA review to coordinate an account launch and switch to your Live API Keys.

For help, please contact us anytime at support@churnbuster.io or via your dedicated Slack channel.


Important note about "source" and "source_id":

  • Wherever you see source in the API docs, set it to "in_house" or another consistent name that references your in-house subscription management system.
  • Wherever you see source_id in the API docs, set it to the ID from within your in-house system, with unique ID's for the Customer, Subscription, Payment Method, etc.
