(Mono C#) 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.

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

// --------------------------------------------------------------------------------------------------------
// Note: There is a large amount of information about the MyInvois API on the Internet.
// The information is found at https://sdk.myinvois.hasil.gov.my/
// and also at many other companies offering solutions.
// 
// Unfortunately, it's all completely useless to the programmer wishing to implement the API.
// The reason it's useless is because no specifics are given.
// A developer needs to know the specific details of the HTTP request and response.
// What is the HTTP request Content-Type?
// What is the endpoint?
// What is the format of request body and response?  JSON or XML?
// What specific header fields are needed, if any?
// 
// Providing samples of raw HTTP requests and responses tells the developer everything he/she needs to know.
// All unknowns become known.  
// Everything becomes easy to implement.
// Just show some sample raw HTTP requests and responses, and we can all spend far less time in the office
// and more time relaxing on a beach.

// 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.

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