Sandbox guide

Testing your integration

While the store is in test mode, use the Simulator card on each invoice's detail page in your dashboard. You can trigger any of the events above (with optional amount override for under/overpaid) without waiting for real chain events. Each click:

1. Updates the invoice status in our DB
2. Fires the matching webhook to your endpoint with livemode: false
3. Pushes the new status over SSE/WebSocket to any open hosted checkout pages

That's it. Once your handler responds 200 for all event types you care about, flip the store toggle to live, register your mainnet xpub, and you're in production.
