Legacy Migration

Current source no longer exposes the old Epusdt order route.

Removed routes

• POST /api/v1/order/create-transaction
• POST /payments/epusdt/v1/order/create-transaction

What to use instead

If you control the client code

Use GMPay:

POST /payments/gmpay/v1/order/create-transaction

If the upstream system only supports redirect-style EPay flows

Use EPay compatible:

GET /payments/epay/v1/order/create-transaction/submit.php
POST /payments/epay/v1/order/create-transaction/submit.php

Migration checklist

• Replace the old endpoint URL
• Add pid to all inbound requests
• Re-sign requests with the merchant row's secret_key
• Stop relying on old docs that mentioned /payments/epusdt/v1/...
• If you need dynamic chain/token UI, fetch /payments/gmpay/v1/config and read data.supported_assets
