Token authentication for CURL in EXCEL VBA - vba

Question

A client requested that I put together a tool to take a company domain name and somehow come up with the account name. I found an API that I can work with, but I'm not as familiar with doing this in VBA.
Here is the CURL procedure that the site documentation gives to push through a Domain Name, and receive the company name as a response:
curl 'https://company.clearbit.com/v2/companies/find?domain=segment.com' \
-u sk_b3b05a8924c4f3df86248b4e38421cfa:
After several attempts of receiving the "Please authenticate your request", I've finally gotten to the point where I am receiving an error from the API, I think indicating that I am now correctly calling the API in some way.
Here is my current code. Any idea why I may be receiving this error?
{"error":{"type":"api_error","message":"Sorry, something went wrong. We have been notified."}}
Public Function CallRestAPI2(strUrl1 As String)
TargetURL = "https://company.clearbit.com/v2/companies/find?domain=toplinegroup.com"
Set HTTPReq = CreateObject("WinHttp.WinHttpRequest.5.1")
'HTTPReq.Option(4) = 13056 '
HTTPReq.Open "GET", TargetURL, False
HTTPReq.SetRequestHeader "Content-Type", "application/json"
HTTPReq.SetRequestHeader "Accept", "application/json"
HTTPReq.Send "-u sk_b3b05a8924c4f3df86248b4e38421cfa"
Debug.Print HTTPReq.responseText
End Function
Any idea what I am doing wrong?

Figured this out after more reading in the documentation and it was due to not passing the Authentication header the correct way. Here is my code:
Public Function CallRestAPI3(strUrl1 As String)
Dim xmlhttp As New MSXML2.XMLHTTP60, myurl As String
myurl = "https://company.clearbit.com/v2/companies/find?domain=toplinegroup.com"
xmlhttp.Open "GET", myurl, False
xmlhttp.setRequestHeader "Authorization", "Bearer " + "sk_b3b05a8924c4f3df86248b4e38421cfa"
xmlhttp.Send
Debug.Print (xmlhttp.responseText)
End Function
