When a PagerDuty incident is triggered, send a message to Slack

This workflow responds to a PagerDuty incident by sending a message to a Slack channel. The urgency of the incident determines which Slack channel the message goes to.

Prerequisites

Before you run this workflow, you will need the following:

• A Slack workspace and a connection configured in Relay to that workspace.
• A PagerDuty account.

Configure the workflow

You may need to update some of the default parameters or connection information in this workflow to run in your environment. The default configuration assumes:

• Your Slack connection is called my-slack-account
• You want high-urgency incidents to go to the #on-call Slack channel
• You want low-urgency incidents to go to the #it Slack channel

Test the workflow

You can test the workflow with dummy data by clicking the Run button. Ensure the message you expect shows up in your Slack workspace. We recommend always testing workflows manually before configuring automated triggers.

Set up the trigger

When you create this workflow for the first time, we'll automatically provision a webhook for you. You need to provide this webhook to PagerDuty to complete the integration.

In the workflow overview page in Relay, find the webhook URL by navigating to the Setup sidebar. Copy the URL to your clipboard.

In PagerDuty, determine which services you want to run the workflow when an incident is triggered. For each of those services:

1. Click on the Integrations tab.
2. At the bottom of the page, click Add or manage extensions.
3. Create a New Extension:
   • Extension Type: Generic V2 Webhook
   • Name: Relay
   • URL: Paste the webhook URL from your clipboard.
4. Click Save.

Whenever an incident is triggered for the first time, this workflow will run. You can reuse the same webhook URL for many services.
