MicrosoftTeams Powershell - OAuth (Non interactive)
To authenticate and access Microsoft Teams using PowerShell with OAuth (non-interactive) authentication, you can use the Microsoft Authentication Library (MSAL) to acquire an access token. Here's an example of how you can accomplish this:
Install the
MSAL.PS
module:- Open a PowerShell session with administrative privileges.
- Run the following command to install the
MSAL.PS
module:powershellInstall-Module -Name MSAL.PS
Import the
MSAL.PS
module:- Run the following command to import the
MSAL.PS
module:powershellImport-Module -Name MSAL.PS
- Run the following command to import the
Create an application in Azure Active Directory (AAD):
- Go to the Azure portal (portal.azure.com) and sign in with your Azure account.
- Create a new Azure AD application and note down the "Application (client) ID" and "Directory (tenant) ID". Configure the necessary permissions and scopes for accessing Microsoft Teams APIs.
- Generate a client secret or certificate for the application and securely store it for authentication.
Use the
MSAL.PS
module to authenticate and acquire an access token:Run the following code snippet, replacing the placeholders with your application details and resource URL:
powershell$clientId = "YOUR_CLIENT_ID"
$tenantId = "YOUR_TENANT_ID"
$clientSecret = "YOUR_CLIENT_SECRET"
$resource = "https://graph.microsoft.com" # Resource URL for Microsoft Teams
$tokenParams = @{
ClientId = $clientId
ClientSecret = $clientSecret
Authority = "https://login.microsoftonline.com/$tenantId"
Scope = "https://graph.microsoft.com/.default"
Resource = $resource
}
$accessToken = Get-MsalToken @tokenParams
Replace
YOUR_CLIENT_ID
,YOUR_TENANT_ID
, andYOUR_CLIENT_SECRET
with the corresponding values from your Azure AD application.
Once you have acquired the access token, you can use it to make authenticated requests to the Microsoft Teams APIs or other Microsoft Graph APIs using PowerShell.
Remember to handle the access token securely, as it provides privileged access to the requested resource. Protect sensitive information such as client secrets and avoid storing them in plain text.
Note that the specific requirements and steps may vary depending on your environment and organization's policies. Consult the Microsoft documentation and Azure portal for more detailed instructions on setting up the Azure AD application and configuring the necessary permissions.
