Demonstrates how to get an OAuth2 access token with an intermediary that is representing a taxpayer (acting on behalf of a specific taxpayer). The OAuth2 access token can then be used to access MyInvois protected APIs. Objective-C

BOOL success = NO;

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

// Sends the following HTTP POST to get a MyInvois OAUth2 access token using client_credentials

// POST /connect/token HTTP/1.1
// Host: preprod-api.myinvois.hasil.gov.my
// Accept: */*
// Content-Length: <<variable>>
// Content-Type: application/x-www-form-urlencoded
// onbehalfof: C25845632020

// client_id={YOUR_CLIENT_ID}&client_secret={YOUR_CLIENT_SECRET}&grant_type=client_credentials&scope=InvoicingAPI

}

// Note: The returned access token is valid for a short amount of time.  Perhaps 1 hour.
// The access token is used in the "Authorization: Bearer <access_token>" header in subsequent requests until it expires.
// Your application would then need to get a new access token, and so on..

// Here's a sample response:

// {

//   "expires_in": 3600,
//   "token_type": "Bearer",
//   "scope": "InvoicingAPI"
