MCsets Payment Gateway for Paymenter

A payment gateway extension for Paymenter that integrates MCsets Enterprise for hosted checkout payments.

---

How It Works

1. Customer clicks Pay on a Paymenter invoice
2. Extension creates a checkout session via the MCsets API
3. Customer is redirected to the MCsets hosted checkout page
4. After payment, customer is sent back to their invoice
5. MCsets fires a webhook → invoice is automatically marked as paid
