# Get the Unrouted Orchestration for an Event Orchestration

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

Get a Global Event Orchestration's Rules for Unrouted events.

An Unrouted Orchestration allows you to create a set of Event Rules that will be evaluated against all events that don't match any rules in the Global Orchestration's Router. Events that reach the Unrouted Orchestration will never be routed to a specific Service.

The Unrouted Orchestration evaluates Events sent to it against each of its rules, beginning with the rules in the "start" set. When a matching rule is found, it can modify and enhance the event and can route the event to another set of rules within this Unrouted Orchestration for further processing.

| `orchestration_path.parent` | object |  |  |
| `orchestration_path.parent.id` |  |  | ID of the Global Event Orchestration this Unrouted Orchestration belongs to. |
| `orchestration_path.parent.type` |  |  | One of: `event_orchestration_reference`. |
| `orchestration_path.sets` |  |  | An Unrouted Orchestration must contain at least a "start" set, but can contain any number of additional sets that are routed to by other rules to form a directional graph. |
| `orchestration_path.catch_all` | object |  |  |
| `orchestration_path.catch_all.actions` | object |  |  |
| `orchestration_path.catch_all.actions.severity` | string |  | Set the severity of the resulting alert. One of: `info`, `error`, `warning`, `critical`. |

| `orchestration_path.catch_all.actions.extractions[].template` | string |  | (option 1) A value that will be used to populate the target PD-CEF field. You can include variables extracted from the payload by using string interpolation. |
| `orchestration_path.catch_all.actions.extractions[].target` | string |  | (option 2) The PD-CEF field that will be set with the value from the regex. |
