// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.HttpRequest')

// See Understanding Scopes in Azure OAuth2 Client Credentials Flow
$req->AddParam('scope','https://graph.microsoft.com/.default');

$req->AddParam('grant_type','client_credentials');

// Note: Your Azure app must be registered as a single-tenant app to use client credentials.
