See more OAuth2 Examples

Demonstrates how to get an OAuth2 access token for an Azure Registered App using the Client Credentials Grant Flow.

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

JavaScript

var success = false;

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

var http = new CkHttp();

var req = new CkHttpRequest();
req.AddParam("client_secret","CLIENT_SECRET");
req.AddParam("client_id","CLIENT_ID");

//  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.
//  Use your own tenant ID, for example 4d8fdd66-66d1-43b0-ae5c-e31b4b7de5cd
var url = "https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token";

var json = new CkJsonObject();

//  Sample successful output:

//  {
