(Ruby) 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.
# Your application would then need to get a new access token, and so on..

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