NoChurn + Any billing, by API

Keep your billing. Send subscriptions, payments and cancellations to NoChurn and get signed webhooks back.

HOW IT WORKS

Connected in three steps

01
Create a test key (nc_test_…) in NoChurn. Test keys never send a real email.
02
Send your customers, subscriptions, payments and cancellations to the REST API, or let your coding agent do it with the NoChurn MCP server.
03
Subscribe to NoChurn webhooks: they tell your billing when to retry, what offer was accepted, or that a customer cancelled.

WHAT NOCHURN DOES

Feature	Done by	How
Failed payments	NoChurn	NoChurn decides when to retry and sends the emails; your billing runs the charge when the webhook says so.
Chargebacks	Uses this data	Send disputes through the API and NoChurn gathers the evidence it has: cancel flow answers, emails sent, usage.
Cancel flows	NoChurn	Reasons, offers and one-click cancel, hosted or headless. Your app calls the API for reasons and offers, then applies the result in your billing.
Win-back	NoChurn	Emails at day 30, 60 and 90, written from the cancel reason, with a link to come back.
Churn score	NoChurn	A 0–100 score at signup and at every change, from the payment method, signup source and your custom data.
Custom data & AI	NoChurn	Your own attributes and usage, sent by API, matched to the same customers.
