Using Slack’s Incoming Webhook, you can send monitor incident notifications to a Slack channel.

Prerequisites: Creating a Slack Incoming Webhook

   Go to Slack API: Applications, select “Create New App”, then choose “From scratch”. Specify an App Name and the workspace where you want to send notifications.

2. Enable Incoming Webhooks

   On the settings page of the app you created, open “Incoming Webhooks” and turn the toggle ON.

3. Generate a Webhook URL

   Click “Add New Webhook to Workspace”, select the channel you want to send notifications to, and click “Allow”.

4. Copy the Webhook URL

Note

The Webhook URL must start with https://hooks.slack.com/. Other URLs will result in an error during configuration.
