I want to retrieve some data from an API using an GET request. The API takes one parameter encoded as JSON in the body of the request. The following code works fine for sending a POST request with some JSON data however if the type of the request is changed to GET the final request being sent contains no body:
Dim strJSONText As String, strURL As String
strURL = "https://<domain>/<some>/<path>"
strJSONText = "{'<parameter>':'<value>'}"
Set objXMLhttp = CreateObject("Msxml2.XMLHTTP")
objXMLhttp.Open "GET", strURL, False
objXMLhttp.setRequestHeader "Accept", "application/json"
objXMLhttp.setRequestHeader "Content-Type", "application/json"
objXMLhttp.send (strJSONText)
Why is strJSONText being ignored whenever the request type is GET? How do I send a GET request with a body using VBA?

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
I have a VBA program that sends REST API request and get response.
I use WinHttp.WinHttpRequest to send request but the response text does not support Japanese.
It means if REST server returns result with Japanese, HTTP response text in VBA will be strange characters (e.g. ?aa??a).
I tried to SetRequestHeader with Accept-Language = ja-JP, Charset = UTF-8...but it does not work.
Please help me to resolve this problem.
My code here:
Dim oHttp As WinHttp.WinHttpRequest
Set oHttp = New WinHttp.WinHttpRequest
oHttp.Open "GET", "url", False
oHttp.SetRequestHeader "Accept", "application/json"
oHttp.SetRequestHeader "Content-Type", "application/json"
oHttp.SetRequestHeader "Authorization", "Bearer <token>")
oHttp.Send (sData)
Debug.Print oHttp.ResponseText
Thanks
I found a solution for that: use ServerXMLHTTP instead of WinHttpRequest.
I would like to post data to Jira using this method :
Private IEService As New MSXML2.XMLHTTP60
Public Function httpPOST(baseUrl As String, url As String, jsonInput As String, auth As String) As String
Dim accept As String
accept = "application/json"
With IEService
.Open "POST", baseUrl & url, False
.setRequestHeader "Content-Type", "application/json"
.setRequestHeader "Accept", accept
.setRequestHeader "Authorization", "Basic " & auth
.setRequestHeader "Origin", baseUrl
.send jsonInput
httpPOST = .responseText
'MsgBox (.responseText)
End With
End Function
Data is fine and the POST is executed on the back end side. But Jira in this instance returns an empty response body.
When this happens VBA crashes on .send jsonInput with error : runtime error -2147467260
Seems like MSXML2 does not handle empty responses. But I haven't found anyone facing same issue searching on the web.
Any ideas what I am doing wrong or how to fix it ?
Thanks
Does anyone know how to construct a POST DATA body in VBA? I'm trying to upload rather lengthy strings via a post call using the "Microsoft.XMLHTTP" object. I'm not tied to using that object for making the HTTP request either.
How about
Dim XMLHttp As Object: Set XMLHttp = CreateObject("Microsoft.XMLHTTP")
XMLHttp.Open "POST", "http://www.lfkfklkf.com", False
XMLHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
XMLHttp.send "q=ploppy&x=cake"
Debug.print XMLHttp.responseText
Set XMLHttp = Nothing
