Request

Using WinHttp.WinHttpRequest

This is built into Windows.
Reference - Microsoft WinHTTP Services v5.1
Supports proxy credentials

Sub Request() 
Dim xmlhttp As WinHttp.WinHttpRequest 
Dim sResponse As String 

   Set xmlhttp = CreateObject("WinHttp.WinHttpRequest.5.1") 
   
   xmlhttp.Open "GET", "https://bettersolutions.com/RestService" 

   xmlhttp.SetAutoLogonPolicy (WinHttp.AutoLogonPolicy_Always) 
   xmlhttp.Send 
   sResponse = xmlhttp.ResponseText 
End Sub 

Using MSXML2.ServerXMLHTTP

This uses a dedicated HTTP client stack

Dim http As Object 
   Set http = CreateObject("MSXML2.ServerXMLHTTP.6.0") 

   http.Open "POST", "https://api.example.com/data", False 
   http.setRequestHeader "Content-Type", "application/json" 
   http.send "{""name"":""Russell""}" 

   Debug.Print http.Status 
   Debug.Print http.responseText 

Using MSXML2.XMLHTTP

This is on its way out
Uses the browser HTTP stack (WinInet), which introduces quirks that can break JSON API calls.
You want the simplest possible GET request
You don't need advanced headers or authentication
Reference - Microsoft XML v6.0
Supports proxy and server credentials

Sub Request() 
Dim xmlhttp As MSXML2.XMLHTTP60 
Dim sDownloadDate As String 
Dim sResponse As String 

   xmlhttp = CreateObject("MSXML2.XMLHTTP60) 
   sDownloadDate = VBA.Format(VBA.Now, "yyyy-mm-dd") 
   
   Call xmlhttp.Open("GET", modConstants.g_sURL_PREFIX & modConstants.g_sURL_SUFFIX_COMBINEDINFO & sDownloadDate, False) 

   xmlhttp.send 
   sResponse = xmlhttp.responseText 
End Sub
