PagerDuty Integration? I'm stuck...

When you create the Escalation Chain, you need to create Stages. In the escalation chain choose the "+" next to Stages to create a new stage. This will popup a "Add new recipients" window. Click on the "+" which asks for a user, pick/type-in a user as mentioned above. Once you pick a user, it will offer a "Contact Method" box to the right where you can pick your PD integration. This will only show up if you pick a normal user, does not work for groups nor api-only users. Click on the white save button then the blue save button.
