{
"responseCode": "00",
"responseMessage": "Successful operation",
"errors": [],
"responseData": {
"status": "COMPLETED"
}
}responseData holds the endpoint result. Inspect responseCode alongside the HTTP status: a successful HTTP exchange can still carry a business error.
For a first integration, read Getting started, then Authentication before making a request. The API reference explains the shared request and response conventions.
Before moving money, implement safe retries, webhook processing, and error recovery. Confirm an uncertain outcome before submitting another payment.
