Testing your integration in the Sandbox environment
The Amazon Pay and Login with Amazon Sandbox environment enables you to thoroughly test your Amazon Pay and Login with Amazon integration before going live. When you test your implementation in Sandbox mode, you can simulate the buyer experience as your buyers navigate through the Amazon Pay widgets on your website.
In Sandbox mode, you can also test your API calls to Amazon to ensure that the calls are configured correctly and that the responses include all the payment parameters that you need to track the entire order. Simulating error conditions helps you to better manage your buyer's experience in the event that something goes wrong during the checkout experience.
