Test vs Production
Understand the current TRON environments without treating test tokens as money.
Production runs against TRON Mainnet. Shasta is a separate test environment and test USDT has no real value. Network identity is fixed per deployment/database so Mainnet and Shasta financial records cannot mix.
The current public production API does not expose a mark-paid or simulated-payment endpoint. The signed integration.test webhook checks connectivity only; it is not proof of a payment. Use only environment switching that your BramaPay deployment explicitly provides.
