NAME

Azure::AD::ClientCredentials - Azure AD Client Credentials authentication flow

SYNOPSIS

            

              
              
use Azure::AD::ClientCredentials;
my $creds = Azure::AD::ClientCredentials->new(
  resource_id => 'https://management.core.windows.net/',
  client_id => '',
  secret_id => '',
  tenant_id => '',
);
say $creds->access_token;
            
          

DESCRIPTION

Implements the Azure AD Client Credentials flow. See Azure::AD::Auth for more information and alternative flows.

ATTRIBUTES

resource_id

The URL for which you want a token extended (the URL of the service which you want to obtain a token for).

https://graph.windows.net/ for using the MS Graph API

https://management.core.windows.net/ for using the Azure Management APIs

tenant_id

The ID of the Azure Active Directory Tenant

client_id

The Client ID (also referred to as the Application ID) of an application

secret_id

A Key assigned to the Client Id.

ad_url

This defaults to https://login.microsoftonline.com, and generally doesn't need to be specified. Azure AD has more endpoints for some clouds:

https://login.chinacloudapi.cn China Cloud

https://login.microsoftonline.us US Gov Cloud

https://login.microsoftonline.de German Cloud

METHODS

access_token

Returns the access token that has to be sent to the APIs you want to access. This is normally sent in the Authentication header of HTTPS requests as a Bearer token.

The access_token is cached in the object as long as it's valid, so subsequent calls to access_token will return the appropriate token without reauthenticating to Azure AD. If the token has expired, access_token will call Azure AD to obtain a new token transparently.

Example usage:

            

              
              
my $auth = Azure::AD::ClientCredentials->new(...);
use HTTP::Tiny;
my $ua = HTTP::Tiny->new;
my $response = $ua->get(
  'http://aservice.com/orders/list', 
  {
    headers => { Authorization => 'Bearer ' . $auth->access_token }
  }
);
