What's the difference between "user" and "user_reference" in PagerDuty API

Question

I'm writing a terraform template to setup escalation policies.

https://www.terraform.io/docs/providers/pagerduty/r/escalation_policy.html

I want to create an escalation policy to a specific user, but I don't know whether to specify user or user_reference as a value of rule.target.type. What's the difference between user and user_reference in PagerDuty API?

Answer 1

As a value of rule.target.type, user and user_reference are one and the same. Using either type should create an escalation policy that involves the specified user that is defined with rule.target.id.
