How to Send Real-Time Alerts via Enterprise WeChat Using Python

Common alert channels include email, phone, SMS, and WeChat; the author prefers Enterprise WeChat for its immediacy.

To create an alert application, log into the web version of Enterprise WeChat, navigate to Application Management → Application → Create Application, upload a logo, set an application name, and define the visible range.

After the app is created, obtain the corporate ID (corpid) from “My Enterprise → Enterprise Information” and retrieve the secret by viewing the app’s secret page.

The integration relies on two API endpoints: one to get an access token ( https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={corpid}&corpsecret={secret} ) and another to send a message ( https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={token} ).

The following Python code defines a WeChatPub class that fetches the token and sends a text‑card message via the above APIs.

<code>import json<br/>import datetime<br/>import requests<br/><br/>CORP_ID = ""
SECRET = ""
<br/>class WeChatPub:
    s = requests.session()
    def __init__(self):
        self.token = self.get_token()
    def get_token(self):
        url = f"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={CORP_ID}&amp;corpsecret={SECRET}"
        rep = self.s.get(url)
        if rep.status_code != 200:
            print("request failed.")
            return
        return json.loads(rep.content)['access_token']
    def send_msg(self, content):
        url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=" + self.token
        header = {"Content-Type": "application/json"}
        form_data = {
            "touser": "@all",
            "toparty": " PartyID1 | PartyID2 ",
            "totag": " TagID1 | TagID2 ",
            "msgtype": "textcard",
            "agentid": 1000002,
            "textcard": {
                "title": "服务异常告警",
                "description": content,
                "url": "URL",
                "btntxt": "更多"
            },
            "safe": 0
        }
        rep = self.s.post(url, data=json.dumps(form_data).encode('utf-8'), headers=header)
        if rep.status_code != 200:
            print("request failed.")
            return
        return json.loads(rep.content)
</code>

Instantiate the class, format the current time, and call send_msg with an HTML‑styled message; the notification will appear instantly on the mobile device if the Enterprise WeChat account has permission.

<code>wechat = WeChatPub()
now = datetime.datetime.now()
timenow = now.strftime('%Y年%m月%d日 %H:%M:%S')
wechat.send_msg(f"<div class=\"gray\">{timenow}</div> <div class=\"normal\">阿里云 cookie 已失效</div><div class=\"highlight\">请尽快更换新的 cookie</div>")
</code>

This simple integration enables real‑time alerting through Enterprise WeChat and is recommended for users who already have a WeChat Work account.
