Choose Your Testing Path
Two ways to start testing once the middleware is running — Postman or the built-in Simulator — both work against a real terminal or the simulator.
Once the middleware is installed and running, pick one of two ways to start testing. Both work against either a real physical terminal or the built-in Simulator, so use whichever tool fits how you work.
Testing with Postman
Best if you're integrating a POS application and want to see exact request/response shapes before writing code. Import the ready-made collection, set a couple of variables, and run requests in order.
→ See Testing via Postman.
Testing with the Simulator
Best if you don't have a physical terminal on hand yet, or want to validate your integration's error handling (declines, timeouts) on demand. It works standalone from the dashboard (no Postman needed), or driven entirely from Postman if you prefer.
→ See Using the built-in Simulator (dashboard) or Using Postman with the Simulator (Postman).
