Sending Photo to Telegram (API / Bot) - vba

Question

I send messages form Excel to telegram. It works nice.
But how can I send a photo? I don't understand it (https://core.telegram.org/bots/api#sendphoto)
Thanks for help!
My send Message:
Dim objRequest As Object
Dim strChatId As String
Dim strMessage As String
Dim strPostData As String
Dim strResponse As String
strChatId = Worksheets("Einstellungen").Cells(3, "AB")
strMessage = Report
APIcode = Worksheets("Einstellungen").Cells(2, "AB")
strPostData = "chat_id=" & strChatId & "&text=" & strMessage
Set objRequest = CreateObject("MSXML2.XMLHTTP")
With objRequest
.Open "POST", "https://api.telegram.org/" & APIcode & "/sendMessage?", False
.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
.send (strPostData)
GetSessionId = .responseText
End With

If your code is working as-is for plain text messages then you should only need to make a couple changes to it.
You're probably currently using the API's sendMessage method, which takes the chat_id and text parameters.
You want to use the sendPhoto method, which tales the chat_id and photo parameters (but no text parameter).
So this is a bit of a shot in the dark since I've never used or heard of Telegram and I don't have a key, so I can't test it, but theoretically, you could send a photo from a URL like this:
Sub telegram_SendPhoto()
Const photoURL = "https://i.imgur.com/0eH6d1v.gif" 'URL of photo
Dim objRequest As Object, strChatId As String, APIcode As String
Dim strPostData As String, strResponse As String
strChatId = Worksheets("Einstellungen").Cells(3, "AB")
APIcode = Worksheets("Einstellungen").Cells(2, "AB")
strPostData = "chat_id=" & strChatId & "&photo=" & photoURL
Set objRequest = CreateObject("MSXML2.XMLHTTP")
With objRequest
.Open "POST", "https://api.telegram.org/" & APIcode & "/sendPhoto?", False
.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
.send (strPostData)
strResponse = .responseText
End With
MsgBox strResponse
End Sub
Pass a file_id as String to send a photo that exists on the Telegram servers (recommended), pass an HTTP URL as a String for Telegram to get a photo from the Internet (above), or upload a new photo using multipart/form-data. More info on Sending Files »
