Testing and Going Live
To test your integration, use the test credentials below. These work in test mode only — no real money is moved. Your test API credentials are available in Command Center — Developer Settings.
If you use pre-authorization, test the authorized outcome too — verify your integration captures or voids the held payment before fulfilling. See Pre-auth and Capture.
