If you haven't created your app yet, head here to create your App.
After you create your app, you need a testing business, that's where our Sandbox businesses come in.
A sandbox business is a testing business with actual items/locations and all needed data to test our APIs.
Head over to Sandbox creates your Sandbox business to authenticate to and use for testing (before testing on a real business).
You will receive the credentials via email with a link to our dashboard, the creation of the sandbox takes a few minutes so please be patient if you can't login and when using the sandbox enter the subdomain in lower case.
