# Get the Router for an Event Orchestration

`GET https://api.pagerduty.com/event_orchestrations/{id}/router`

Get a Global Orchestration's Routing Rules.

An Orchestration Router allows you to create a set of Event Rules. The Router evaluates Events you send to this Global Orchestration against each of its rules, one at a time, and routes the event to a specific Service based on the first rule that matches. If an event doesn't match any rules, it'll be sent to service specified in as the `catch_all` or the "Unrouted" Orchestration if no service is specified.

For more information see the [API Concepts Document](https://docs.pagerduty.com/developer/api-concepts#event-orchestrations)
