  flows in the browser without writing code, using Inyo's hosted gateway
  simulator.

# Playground

Try the Inyo Payment Gateway end to end without writing any code. The simulator below runs against the **sandbox** environment, so you can explore the authentication, tokenization, and payment flows safely — no real money moves and no production credentials are required.

> **Sandbox only.** The playground talks to the gateway sandbox. Use your sandbox credentials and the [test data](apis/test-data/cards.md) when prompted. Never enter production keys or real card numbers here.
