Once your Checkout form can submit payments, you’ll want to verify their outcome on your server.
You can also use our demo server until you have implemented your own:
When a payment is authorised, your server needs to request the

/verify endpoint. In the request, include your API Key, which you copied down in Step 1.
Test your integration
Before going live, use our test card numbers to test your integration. We recommend testing each payment method that you intend to offer your shoppers.
You can test the status of a test payment in your Customer Area > Payments.
You've integrated Checkout into your iOS app! But there are a few things you should do before going live.
