Intune Data warehouse error

Question

Hi,

I've been trying to access the intune data warehouse API. I can get the basic metadata, but not the different entities/collections.
I authenticate via Oauth2 and an app registration that has all the required application API permissions (that I found here: https://learn.microsoft.com/en-gb/mem/intune/developer/intune-graph-apis?WT.mc_id=Portal-Microsoft_AAD_RegisteredApps#intune-permission-scopes , plus the get_data_warehouse permission). I also set 'Allow access to unlicensed admins' to yes in Intune.
This is the error I recieve when calling, for example, ' https://fef.msub05.manage.microsoft.com/ReportingService/DataWarehouseFEService/devices?api-version=v1.0 ' :

{
	"ErrorCode":"Forbidden",
	"Message":"{\r\n  \"_version\": 3,\r\n  \"Message\": \"An error has occurred -

Answer 1

@Timo De Grande, Thanks for posting in Q&A. From the error message, it shows forbidden which means permission issue. Please check if the permissions in the following link are also granted. If not, grant them and see if it is working.

https://learn.microsoft.com/en-us/mem/intune/developer/reports-proc-data-rest#grant-the-client-app-access-to-the-microsoft-intune-api

Hope the above information can help.
