Build confidently in the sandbox.

The API is available for registered merchant workspaces. Create a test payment intent, simulate success or failure, and retrieve its state from your server. Sandbox records are separate from financial reports and never move money.

Quickstart ↗

Make your first API call in a few steps.

Authentication ↗

Create, scope, expire and revoke your keys.

Payment intents ↗

Build and test a complete payment state flow.

Errors & retries ↗

Handle failures and repeat requests safely.

All requests use HTTPS and a server-side bearer secret. Responses are JSON; timestamps use Unix milliseconds. The current sandbox supports USD amounts in integer cents.
