To use Microsoft's APIs to monitor your MTR (Microsoft Teams Rooms), you need to:

• Create an Azure AD application and assign the appropriate permissions.
• Declare an external service of type Ms Graph in Zebrix Control.
• Create and configure your devices.

Start by creating the Azure AD application and the external service by following this guide: Ms Graph External Service

Then, add the devices by configuring their MTR drivers:

1. Device ID: The device ID from Microsoft
2. Zebrix Control External service name compatible with MS Graph

You can use one of the following methods:

Use PowerShell or another language to call the endpoint (in beta):

`https://graph.microsoft.com/beta/teamwork/devices`

Example in PowerShell:

$token = "YOUR_ACCESS_TOKEN"
$headers = @{ Authorization = "Bearer $token" }
$devices = Invoke-RestMethod -Method Get -Uri "https://graph.microsoft.com/beta/teamwork/devices" -Headers $headers
$devices | ConvertTo-Json

• Log in to Graph Explorer
• Go to API Explorer
• Enable beta APIs
• Perform a GET request on the teamwork/devices API
• Find your device in the list and note its ID

Using these methods, you can easily retrieve your Microsoft Teams ID.

The probe must be able to establish outbound connections (https, 443) to 'https://graph.microsoft.com'.
