Overview

Description

The gateway redirects customers to the hosted Cryptomus checkout page and automatically updates transactions through signed webhook notifications.

The integration verifies webhook signatures, transaction IDs, payment amounts, currencies, and Cryptomus payment identifiers before approving an order. It supports payment status synchronization, underpayments, overpayments, failed payments, completed refunds reported by Cryptomus, IC5 fraud checks, and configurable invoice lifetime, cryptocurrency, and blockchain network.

Recurring payments and automatic refunds from IC5 are not supported. Refunds must be processed through the Cryptomus merchant dashboard because a destination cryptocurrency address is required.
