The PagerdutyHook can be used to interact with both the PagerDuty API and the PagerDuty Events API.
Takes both PagerDuty API token directly and connection that has PagerDuty API token.
If both supplied, PagerDuty API token will be used.
In these cases, the PagerDuty API token refers to an account token:
