To access these Blueprints, you must enable the Online Subsystem Oculus in Edit > Plugin > Online Platform.

• Verify Entitlements - verifies the user is authorized to run the application.
• Get Oculus Identity - returns Oculus ID and Oculus username as strings; provides flow control for On Success/On Failure

In this simple example of the Verify Entitlement Blueprint, the application will verify that the user has an entitlement when the application launches, and quit if the check fails. In reality, we recommend providing an appropriate error message before shutting down.

This example of the Get Oculus Identity Blueprint illustrates how to print the user’s Oculus ID to the log or screen.
