# Test the integration

> Verify API, checkout, and webhook integration end-to-end.

## Prerequisites

* API key and settlement wallet configured
* Webhook endpoint or WooCommerce plugin connected

## Checklist

1. **Health check** — `GET https://api.meum.io/health` returns `{ "status": "ok" }`
2. **Create invoice** — `POST /v1/invoices` returns HTTP 201 with `checkout_url`
3. **Checkout loads** — open `pay.meum.io/{invoiceId}` without errors
4. **Payment completes** — invoice status becomes `paid`
5. **Webhook received** — your endpoint returns HTTP 200 with valid signature verification
6. **Order updated** (WooCommerce) — WooCommerce order status becomes `processing` after `payment_complete()`

<Info>
  In development or staging environments, payment detection may behave differently than production.

## Expected result

All checklist items pass in your target environment.
