# Testing

Testing utilities for simulating devices and card taps. Available on playground only — not in production.

## Simulate card tap

 - [POST /ipp/v1/dev/sessions/{sessionId}/simulate-tap](https://docs.kustom.co/contents/api/in-person-payments/testing/simulatecardtap.md): Simulates a physical card tap on the terminal reader, bypassing the need for real hardware. Uses Stripe test helpers to simulate a card-present payment with the requested outcome. Only available in non-production environments.

## Create simulated device

 - [POST /ipp/v1/dev/devices](https://docs.kustom.co/contents/api/in-person-payments/testing/createsimulateddevice.md): Creates a simulated device by generating an enrollment and immediately registering it. Always adds simulated=true to the device metadata. Only available in non-production environments.
