Zoho API in Excel

Zoho API in Excel

I'm trying to use Zoho CRM's API to suck data directly into Excel using a web query.
I can see the the xml in the message box, but the value doesn't go in my sheet.
Thanks

VBA:
  Dim sUri As String
  Dim i As Integer

  Dim objElem As MSXML2.IXMLDOMElement

  sUri = "https://crm.zoho.com/crm/private/xml/Leads/getSearchRecords?authtoken=xxxxxxxx1&scope=crmapi%20&selectColumns=Leads(First%20Name,Last%20Name,Email,Company)&searchCondition=(Email|=|FVINCENT@2COM.FR)"
  Set http = CreateObject("MSXML2.ServerXMLHTTP")
  Set objXML = CreateObject("MSXML2.DomDocument")
  'MsgBox http.responseText
  http.Open "POST", sUri, False
  http.setRequestHeader "Content-Type", "text/xml"
  http.Send "https://crm.zoho.com/crm/private/xml/Leads/getSearchRecords?authtoken=xxxxxxxxxx&scope=crmapi%20&selectColumns=Leads(First%20Name,Last%20Name,Email,Company)&searchCondition=(Email|=|FVINCENT@2COM.FR)"
  MsgBox http.responseText
  objXML.LoadXML (http.responseText)

  Cells(9, 3) = "First Name"
  Cells(9, 4) = "Last Name"
  Cells(9, 5) = "Company"
  x = 11
  
  Set NodeList = objXML.SelectNodes("//Leads")

  For Each Node In NodeList
  Set childNode = Node.SelectSingleNode("//Leads")

      Cells(x, 3) = Node.getAttribute("First Name")
      Cells(x, 4) = Node.getAttribute("Last Name")
      Cells(x, 5) = Node.getAttribute("Company")
      x = x + 1
  Next
