Post alerts on Slack

Post alerts on Slack#

If you are a member of a Slack workspace, you can add a channel and make it private. Then follow these steps:

1. Create a Slack App#

  • Go to Slack API Apps

  • Click “Create New App” and follow the prompts

2. Configure OAuth & Permissions#

  • Navigate to “OAuth & Permissions” in your app settings

  • Add the necessary scopes for your app (e.g., chat:write, channels:read, groups:read)

3. Install the App to Your Workspace#

  • Click “Install App to Workspace”

  • Authorize the required permissions

4. Get Your OAuth Token#

  • After installation, copy the OAuth token provided

  • Use this token to authenticate API requests

5. Post Alerts to Slack#

  • Invite the app to your channel typing invite @name_of_your_app

  • Use the Slack API or a library (like slack_sdk in Python) to send messages to your private channel

Example code#

from slack_sdk import WebClient
from slack_sdk.errors import SlackApiError
from credentials import load_credentials, get_credential

# Load credentials from credentials.txt
load_credentials()

# Get credentials
SLACK_BOT_TOKEN = get_credential('SLACK_WEBHOOK')  # From credentials.txt
CHANNEL_ID = get_credential('SLACK_CHANNEL_ID')     # From credentials.txt

# Initialize Slack client
client = WebClient(token=SLACK_BOT_TOKEN)

def post_message(text):
    """Send a message to Slack channel"""
    try:
        response = client.chat_postMessage(
            channel=CHANNEL_ID,
            text=text
        )
        print("✅ Message sent, ts:", response["ts"])
    except SlackApiError as e:
        print("❌ Slack error:", e.response["error"])

# Example usage
post_message('Hello from ACME alerts!')

Finally go on the settings of the channel and activate share link to invite other members of your group
