Hey @Marsh,
I reached out to the API team and got the following information:
To obtain your API application information:
Go to your Developer Dashboard.
Click on + New Application.
Name the application and click on Create Application.We’ll auto-generate the information needed for integration. The Location ID(s) for your Square account can be found in the Locations tab of your Developer Dashboard.Please note that you may need to switch between “Sandbox” and “Production” with the toggle at the top of the page, depending on the context and your credentials are different for each environment.
