Send a Twilio SMS when PagerDuty incident triggers

This workflow responds to a PagerDuty incident by sending an SMS message to a phone number you define.

Prerequisites

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

• A Twilio account with a phone number provisioned for sending an SMS.
• A PagerDuty account.

Configure the workflow

You will need to update some of the default parameters and secrets in this workflow to run in your environment.

• Set the phoneNumber parameter to the number that you want the message delivered to by default.
• Set the twilioAccountSID secret to the SID of your Twilio account.
• Set the twilioAuthToken secret to the auth token for your Twilio account.
• Set the twilioPhoneNumber secret to the phone number provisioned in Twilio for sending SMS messages.

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.
