When testing Tap to Pay in the sandbox environment, follow the steps outlined below to perform your simulations.

Terminal Registration

You do not need a physical device to perform sandbox testing. To simulate terminal registration:

1. Send a registration request with any arbitrary value for the appDeviceId in the request body.
2. Upon receiving a successful response, contact the Ezypay team to activate the device on the backend.
3. Once activated, a terminal_registration webhook will be triggered and returned to your system, confirming the successful registration of the test device.

Terminal Invoice Simulation

In the sandbox environment, terminal invoices will return a PAID status for any entered amount, except for the specific values listed below. These amounts are preconfigured to simulate common payment failures, allowing you to test your error handling logic.
