Revtain is a payment recovery engine. When a charge fails on your gateway, Revtain runs intelligent retries with prediction-driven timing directly against the gateway that issued the original token. Your checkout doesn’t change. Your customers don’t see anything different. You receive a webhook when the payment is recovered. These docs cover everything you need to integrate Revtain — whether you’re using a supported billing platform (no code) or wiring it up to your own.

​
Get Started

Zero-Code Connectors

Using Chargebee, Recurly, Stripe Billing, Braintree, Zuora, or Shopify (ReCharge)? Paste one webhook URL. No code. 5 minutes.

API Integration

Custom billing system or want full control? Recover your first payment in 60 seconds.
Revtain provisions your account for you — a hands-off step that typically completes the same business day. Once your credentials are issued, a connector integration is a single webhook URL paste; an API integration is one endpoint to call.

How Revtain Fits Your Stack

Revtain sits behind your existing gateway. You keep your checkout, your tokens, and your billing system. When a payment fails, you pass the gateway token to Revtain — Revtain retries the same gateway with ML-optimised timing and returns the result. Tokens are gateway-native (e.g. Stripe pm_xxx retries on Stripe). Nothing about your checkout or PCI scope changes.
