# Mark a ticket as a reference

`PUT /v1/tickets/{ticket_id}/reference`

Requires role member or higher.

Marks the ticket for the whole organization, to find it again when a similar problem appears. Idempotent: marking it again keeps the first time. The ticket itself does not change, and it is still deleted when the plan's retention ends.

## Authentication

A session token: `Authorization: Bearer <session token>`, or the session cookie in the browser. Requires role `member` or higher.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `ticket_id` | path | string | yes |  |
