Application Access

An application's access level determines which users and content your app may access. By default, an application can only successfully interact with the content of its Service Account and any App Users. To also access existing Managed Users of an enterprise, navigate to the Application Access settings accessible via the Configuration tab of the Developer console and set to App + Enterprise Access.

Application Scopes

An application's scopes determine which endpoints and resources an application can successfully call. See the scopes guide for detailed information on each option.

CORS Domains

If your application makes API calls from front-end browser code in Javascript, the domain that these calls are made from will need to be added to an allow-list due to Cross Origin Resource Sharing, also known as CORS. If all requests will be made from server-side code, you may skip this section.

To add the full URI(s) to the allow-list, navigate to the CORS Domain section at the bottom of the Configuration tab in the Developer console.
