I am trying to add and/or update single items in a sharepoint list via VBA and I found a similar question: Import Sharepoint 2010 list data from Excel table using VBA
Bu
Sub Add_Item(ListName As String, SharepointUrl As String, ValueVar As String, FieldNameVar As String)
Dim objXMLHTTP As MSXML2.XMLHTTP
Dim strListNameOrGuid As String
Dim strBatchXml As String
Dim strSoapBody As String
Set objXMLHTTP = New MSXML2.XMLHTTP
strListNameOrGuid = ListName
'Add New Item'
strBatchXml = "<Batch OnError='Continue'><Method ID='3' Cmd='New'><Field Name='ID'>New</Field><Field Name=" + FieldNameVar + ">" + ValueVar + "</Field></Method></Batch>"
objXMLHTTP.Open "POST", SharepointUrl + "_vti_bin/Lists.asmx", False
objXMLHTTP.setRequestHeader "Content-Type", "text/xml; charset=""UTF-8"""
objXMLHTTP.setRequestHeader "SOAPAction", "http://schemas.microsoft.com/sharepoint/soap/UpdateListItems"
strSoapBody = "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " _
& "xmlns:xsd='http://www.w3.org/2001/XMLSchema' " _
& "xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'><soap:Body><UpdateListItems " _
& "xmlns='http://schemas.microsoft.com/sharepoint/soap/'><listName>" & strListNameOrGuid _
& "</listName><updates>" & strBatchXml & "</updates></UpdateListItems></soap:Body></soap:Envelope>"
objXMLHTTP.send strSoapBody
If objXMLHTTP.Status = 200 Then
' Do something with response
End If
Set objXMLHTTP = Nothing
End Sub
Now i got it. This is how you can Add items to a sharepoint list. FieldNameVar is the name of a Field you have to put something in (for example could this Value be 'Title') and ValueVar is the Value you put in the FieldNameVar field.
