Sending Alerts to Slack

Many operations teams use Slack to notify themselves of production issues. Prismatic alert webhooks can be configured to send messages to a Slack channel.

To send alerts as messages to Slack, first generate a new Slack webhook:

1. Navigate to https://api.slack.com/apps
2. Click Create New App, adding an app to your workspace.
3. Under Add features and functionality select Incoming Webhooks
4. Activate Incoming Webhooks and then Add New Webhook to Workspace
5. Take note of the Webhook URL. It should be of the form https://hooks.slack.com/services/foo/bar/baz

Use the Slack webhook URL that you generated in a Prismatic alert webhook, and configure the payload template to read similar to this:

{
  "text": "$NAME triggered - $INSTANCE failed to run. See $URL"
}

No special headers are required for this alert webhook. When an alert monitor that uses the alert webhook next fires, a message will be sent to your Slack channel.
