What level of privileges is required to authenticate a ZDX tenant with MSFT Graph API?

The level of privileges required to authenticate a ZDX tenant with Microsoft Graph API involves both user permissions and the ability to access specific call records. This combination is essential because the Microsoft Graph API enables applications to access Microsoft Cloud service resources and user data. In this case, having user permissions ensures that the application can authenticate and interact with the user's data, while the call record access allows the retrieval of specific communication data relevant to the ZDX (Zscaler Digital Experience) functionality.

By requiring user and call record privileges, the setup allows comprehensive access needed for ZDX’s operational capabilities, enabling it to monitor and enhance the digital experience through telemetry data drawn from Microsoft services. This approach maintains a balance between security and functionality, ensuring that access to sensitive data is managed appropriately while still enabling necessary operations.

The other privilege levels proposed do not capture the required combination of access needed for effective authentication and data retrieval through the Graph API. For instance, full control may suggest overly broad permissions that are not necessary or secure for this task, while read-only access would limit the ability to perform essential operations. This specificity in required privileges ensures that only relevant actions are performed, maintaining both security and functionality within the system.
