OxaPay Gateway for Paymenter

A production-ready cryptocurrency payment gateway for Paymenter, integrating directly with the official OxaPay Merchant Invoice API.

This gateway allows customers to pay invoices using cryptocurrency and enables automatic invoice settlement and service provisioning with zero manual intervention.

3. After successful payment:
   • Customer is redirected back to the invoice
   • OxaPay sends a webhook to Paymenter
4. Invoice is marked Paid
