MyInvois Malaysia Login as Intermediary System

See more Malaysia MyInvois Examples

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. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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

  final http = CkHttp();

  final req = CkHttpRequest();

  req.addHeader('onbehalfof', 'C25845632020');

  req.addParam('grant_type', 'client_credentials');
  req.addParam('client_id', 'YOUR_CLIENT_ID');
  req.addParam('client_secret', 'YOUR_CLIENT_SECRET');
  req.addParam('scope', 'InvoicingAPI');

  req.httpVerb = 'POST';
  req.contentType = 'application/x-www-form-urlencoded';

  final resp = CkHttpResponse();
  try {
    http.httpReq('https://preprod-api.myinvois.hasil.gov.my/connect/token', req, resp);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // 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..

  print('Response Status Code: ${resp.statusCode}');
  print('Response Body:');
  print(resp.bodyStr);

  // Here's a sample response:

  // {
  //   "access_token": "eyJhbGciOiJSUzI1...",
  //   "expires_in": 3600,
  //   "token_type": "Bearer",
  //   "scope": "InvoicingAPI"
  // }

  final json = CkJsonObject();
  json.load(resp.bodyStr);
  final accessToken = json.stringOf('access_token');
