Revtain is a payment recovery engine. When a charge fails on your gateway, Revtain takes the same payment, intelligently routes it across a cascade of acquirers, and captures the revenue your gateway couldn’t. 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.
