WinHttp.WinHttpRequest.5.1 help

[toxicvn]

I'm trying to write code to do a POST HTTP Request to a website. The POST HTTP Request with their API looks like this:

<form method='post' 
    action='https://www.sysdevx.com/api/GetAllVehicles.php'>
  <input type='text' name='login' value='your_login' />
  <input type='text' name='password' value='your_password' />
  <input type='submit'>
</form>

Here is a section with my corresponding code:

hr = CLSIDFromProgID(L"WinHttp.WinHttpRequest.5.1", &clsid);

        if (SUCCEEDED(hr))
        {
            hr = CoCreateInstance(clsid, NULL, 
                                  CLSCTX_INPROC_SERVER, 
                                  IID_IWinHttpRequest, 
                                  (void **)&pIWinHttpRequest);
        }
        if (SUCCEEDED(hr))
        {   // Open WinHttpRequest.
            BSTR bstrMethod  = SysAllocString(L"POST");
            BSTR bstrUrl = SysAllocString(L"https://www.sysdevx.com/api/GetAllVehicles.php");       
            hr = pIWinHttpRequest->Open(bstrMethod, bstrUrl, varFalse);
            SysFreeString(bstrMethod);
            SysFreeString(bstrUrl);
        }
        if (SUCCEEDED(hr))
        {   // Send Request.

            pIWinHttpRequest->SetRequestHeader("Login", "my_login");
            pIWinHttpRequest->SetRequestHeader("Password", "my_password");
            
            hr = pIWinHttpRequest->Send(varEmpty);
        }
        if (SUCCEEDED(hr))
        {   // Get Response text.
            hr = pIWinHttpRequest->get_ResponseText(&result);   
        }
        
        // Print response to console.
        wprintf(L"%.256s",result);

The response is an XML response:

<?xml version ="1.0" encoding = "UTF-8"?>

<response><status code = "103" msg="No devices for this account"/></response>

Am I not sending the username/password correctly? Should I be using SetCredentials instead of SetRequestHeader? I'm not sure if my Send is correct either. I do know however that while this is a valid response, it is the incorrect one because I could just take out the username/pwd lines and I still get the above response. Also, my response is different when I test it on their website forms....

Anyway, what am I doing wrong here? Let me know if you need more info but I'm basically just trying to see if I'm doing an HTTP POST correctly. Thanks.

What did this have to do with AutoIt?
