First, you'll need to set up a new incoming webhook in your team's PagerDuty configuration. An incoming webhook is a method for PagerDuty to receive incoming messages to be posted to your PagerDuty team from external services.
Now you can add your PagerDuty's webhook to the integrations' section:
integrations: pagerduty: - url: url1 - url: url2
You can also go further and connect other popular Polyaxon integrations to Pagerduty using Zapier.
