Access the Microsoft Graph with a script

In a recent article I showed how to connect to the Microsoft Graph in a web browser:

Using the Microsoft Graph Explorer

I also showed how you could do the same:

Using Interactive PowerShell

This article is going to focus on how you can do the same thing but directly via a script that won’t prompt you for credentials.

Before running this script you’ll need to follow the Using Interactive PowerShell article and set up an app in your Azure AD.



During that process you’ll need to record three things that will be used here:

1. Application ID

2. Tenant ID

3. Client secret

I borrowed the connection piece of this script from:

which I found really handy in helping me understand all this. You can download my script from my GitHub repository here:

You’ll need to enter your own Application ID, Tenant ID and Client secret in the variables section. After that, all you need to do is run the script. The results for the query of /security/alerts will end up in a variable called $query which you can view. The actual content of the alerts you’ll find in $query.content.


This Graph connection script should now allow you to connect to the Microsoft Graph for a tenant and start running queries and returning values for entries in there. At the moment it only queries security alerts, but you can modify it to query anything in the Graph for your tenant.
