    // 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

    // --------------------------------------------------------------------------------------------------------
    // 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.
