Intune – Unable to reliably validate application installation status via Microsoft Graph APIs
Hi Everyone, I am working on application deployment and validation using Microsoft Intune, and I am trying to implement an automated validation step to confirm whether applications are successfully installed. My primary requirement Verify application installation status Confirm per‑device installation status Validate installation for specific Intune‑managed devices Use Graph APIs as part of an automation workflow APIs tested so far 1️⃣ App installation status per device (NOT working / not usable) I initially tried using the documented API: HTTP GET https://graph.microsoft.com/beta/deviceAppManagement/mobileApps/{mobileAppId}/deviceStatuses Issue: This API is not working for us It either returns no data or behaves as if it is not a valid / usable endpoint It does not return reliable installation status Hence, we cannot use this API for validation in automation At this point, deviceStatuses is not usable as a primary source of truth in our environment. 2️⃣ Detected Apps (secondary confirmation only) We are also using the Detected Apps API: HTTP GET /deviceManagement/managedDevices/{deviceId}/detectedApps This does work, however: It only confirms app presence It does not confirm Intune assignment or installation intent We are using it strictly as a secondary confirmation, not a primary validation method 3️⃣ Intune internal API observed via browser inspection We also tested the API that appears to be used internally by the Intune portal: HTTP GET https://graph.microsoft.com/beta/users/{user-id}/mobileAppIntentAndStates/{device-id} Observations: The API returns data However, installState frequently shows unknown The Intune portal shows a different and final status (Installed / Failed / Pending) This makes the API unreliable for automation It appears to be troubleshooting‑oriented, not intended for reporting or validation Questions I am looking for guidance on Is deviceStatuses known to be unreliable, tenant‑dependent, or effectively unsupported? What is the recommended API to retrieve actual app installation status per device? Are there any v1.0 APIs available for: Device‑level app installation status? User‑level app installation validation? What is Microsoft’s recommended best practice to validate Intune‑installed applications via automation? Is there official documentation that clearly explains: Which API should be used for reporting vs troubleshooting Expected delays or data inconsistencies between Graph APIs and the Intune portal Goal The goal is to build a reliable and supported automation‑based validation mechanism to confirm that Intune‑deployed applications are successfully installed on target devices. Any official guidance, confirmation of known limitations, or alternative approaches would be very helpful. Thanks in advance for your support.
