Sandbox & testing

The sandbox environment is the integration target before going live. It runs against the Mozrest POS simulator, which behaves like a real POS but is fully under our control - useful for exercising both happy-path and failure-mode scenarios.

Endpoints

Resource	URL
Sandbox API base URL	https://api-sandbox.mozrest.com
Mozrest POS simulator	https://pos.sandbox.mozrest.com

You do not call the simulator directly - it sits behind the Mozrest API as the simulated underlying POS.

Simulator UI

The simulator exposes a "Pay-at-Table activity" UI showing your fetches and payments per venue/table in real time. Useful for debugging during integration.

Failure-mode toggles

Per-venue failure-mode toggles on the simulator (slow-bill mode, reject-payments mode) let us exercise resilience paths on demand. Ask if you'd like a flake injected for a specific test.

Credentials

Your sandbox API token (fixed, non-expiring) and the venue UUIDs in your scope are issued out-of-band by the Mozrest team.
