How do you re-assign a primary user to an Intune device with the Graph API

Question

We're struggling with finding a way to use the Graph API to re-assign a primary user to a device in Intune. We've built a custom loaning center application where we'd need to replace the primary user whenever a device is checked out so that the customer can access the Company Portal.

 

We've tried a variety of API actions, most of which existed in the beta version of the API, which no longer exist or are no longer options. Including:

 

https://graph.microsoft.com/v1.0/deviceManagement/windowsAutopilotDeviceIdentities/{windowsAutopilotDeviceIdentityId}/assignUserToDevice

 

Patching this with the body of the request being the userPrincipalName:

 

https://graph.microsoft.com/v1.0/deviceManagement/managedDevices/{managedDeviceId}

 

The last one looks like it should work, but we get an error when running it.  Does anyone have thoughts on how to get this to work, assuming it can or we should be able to do it

Answer 1

@Samuel Tarr I find someone else provided a solution. Please try and check if it is helpful.

POST https://graph.microsoft.com/v1.0/deviceManagement/managedDevices('{deviceId}')/users/$ref

and a body of

{"@odata.id": "https://graph.microsoft.com/v1.0/users/{userID}"}

Hope it will help.

@Samuel Tarr Thanks for posting in our Q&A.

For this issue, did you consider using PowerShell scripts to make it? If yes, please refer to the following link:
