Commercial payment-system integration is used when an exchange service needs to connect a bank, crypto processor, merchant provider, aggregator, or internal payment gateway that is not included in the standard iEXExchanger package.
We review the provider API, define deposit and payout logic, configure status processing, callbacks or webhooks, errors, timeouts, and repeated payment checks. Separate attention is given to partial payments, cancellations, expired orders, and amount mismatches.
The result is an integration adapted to real exchange-business workflows: correct order creation, reliable payment confirmation, clear event history, and a predictable testing path before production launch.
