Rust Requires Chilkat v11.0.0+

Microsoft Teams OAuth2 Client Credentials Authentication

See more Microsoft Teams Examples

Demonstrates how to authenticate with OAuth 2.0 using the client credentials grant type. Rust

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

let http = chilkat::Http::new();

// Provide the information needed for Chilkat to automatically fetch the OAuth2.0 
// access token as needed.
// This is the new "Integrated OAuth2 Client Credentials" feature introduced in Chilkat v9.5.0.96.  
let json_o_auth_cc = chilkat::JsonObject::new();

// You'll need to have registered an app in Azure beforehand.
// 
// Note: Creating a Team requires the following Application permissions:
// Team.Create, Teamwork.Migrate.All, Group.ReadWrite.All**, Directory.ReadWrite.All**
// 
// See How to Create an Azure App Registration for OAuth 2.0 Client Credentials
// --------------------------------------------------------------------------------------------------------

// Use the values from your App Registration in Azure.

// You'll always use this scope for client credentials, because the allowed actions
// are determined by the App Permissions defined when you registered the app in Azure.
let _ = json_o_auth_cc.update_string("scope", "https://graph.microsoft.com/.default");

// The token endpoint includes your tenant ID.  Use your tenant ID (not the tenant ID shown here).

// To create a Microsoft Team, we want to send an HTTP request like the following:
// 
// Note: The following is the minimal JSON for a request using Applicaton permissions (i.e. the access token retrieved using the client credentials grant).
// 
// POST https://graph.microsoft.com/v1.0/teams
// Content-Type: application/json
// 
// {
//    "template@odata.bind":"https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
