Microsoft Graph has been an increasingly important tool when working with automation tasks. With its many APIs, Graph has become a gem in the automation toolbox, with one single interface to interact with all sort of data.

To simplify access to Microsoft Graph, I have written a PowerShell module, EasyGraph. The module provides a simple way of connecting and querying Microsoft Graph, in a similar way as for example the AzureAD module. The module works cross-platform and the source code is available on GitHub. It is installed directly from PowerShell Gallery:

Install-Module -Name EasyGraph

The EasyGraph module allows several different types of authentication, both interactive and silent, purposed for automation and background jobs.

• Certificate based authentication with thumbprint (Windows only)
• Certificate based authentication with Pfx file
• Username and password (Windows only)
• Client credentials
• Device Code

You also need to register an application in the Azure portal in order to use the module.  In the application you also have to delegate the permissions needed for your script.

Detailed information about the module is available in the EasyGraph repository on GitHub. Below is a simple example on how we for example could update some user attributes of all users in AzureAD.

# Load the module
Import-Module -Name EasyGraph

# We need the ClientId/AppId from the App you created in AzureAD
$MyApp = 'a72b9508-6cbc-4117-b6d7-ff69cf248290'

# Connect using the username+password method
Connect-EasyGraph -AppId $MyApp

# Define whe attributes we want to update
$NewAttributes = @{
    city       = 'Stockholm'
    postalCode = '11130'
}

# Get all users and loop through them
Invoke-EasyGraphRequest -Resource '/users' | Foreach-Object {
    # For each user, get the id ($_.id) and call Graph to set the new attributes
    Invoke-EasyGraphRequest -Resource "/users/$($_.id)" -Method PATCH -Body $NewAttributes
}

# All done, disconnect
Disconnect-EasyGraph

With this simple example it is now up to you to come up with the next big thing, that unleash the power of Microsoft Graph. Happy coding!
