如何通过 Rest API（传入 webhook）回复 Microsoft Teams 频道中的现有消息？

Question

I am able to post a message to a team channel using incoming webhook(code sample below). What I am trying to achieve next is to reply to the same message whenever I have a new update. It's just a simple message in reply and need not to be conversational bot. I tried searching and found some options like teams bot and microsoft graph api. I wanted to know if there is a straightforward way to do it using incoming webhook or something else before exploring this options.

import requests
import json
from urllib.request import Request, urlopen, URLError, HTTPError

webhookurl = "https://factset.webhook.office.com/webhookb2/******************"
message = {
            "@type": "MessageCard",
            "@context": "http://schema.org/extensions",
            "themeColor": "FF0000",
            "summary": "Event Happened",
            "sections": [
                {
                    "activityTitle": "Main Title",
                    "activitySubtitle": "Sub title",
                    "markdown": True,
                    "facts": [
                        {
                            "name": "Start Time (UTC)",
                            "value": "2021-06-11 05:48:10"
                        },
                        {
                            "name": "Last Updated Time (UTC)",
                            "value": "2021-06-11 06:16:15"
                        }
                    ] 
                },
        }

req = Request(webhookurl, data=json.dumps(message).encode("utf-8"),
                headers={"content-type": "application/json"})
try:
    response = urlopen(req)
    response.read()
except HTTPError as e:
    print("Request failed : ", e.code, e.reason)
except URLError as e:
    print("Server connection failed: ", e.reason, e.reason)

Answer 1

Currently Webhook doesn`t support to send back message. This can be done by using Graph API . You can raise UserVoice if this needs to be considered as a future request.

I was able to do it via microsoft graph using delegated workflow. Get access on behalf of a user
