:::endpoint PUT /v1/admin/tickets/{ticket}

A new subject, a new priority, or both. Only what you send changes, so
renaming a ticket never puts back a priority a colleague changed meanwhile.

The trader sees a new subject too, in their own list of tickets. Write it for
them.

Answers with the [ticket](/docs/api/admin/ticket) as it is now.

Needs a firm. Our own staff name one with the `Propper-Workspace` header.

## Request

| Field      | Description |
| ---------- | ----------- |
| `subject`  | Up to 150 characters. Not empty when sent |
| `priority` | `low`, `normal`, `high` or `urgent` |

```bash
curl -X PUT "https://api.proppertrading.com/v1/admin/tickets/tkt_cbqjrnz84cq45ca7" \
  -H "Authorization: Bearer ptat_9f2c1a44_3b8e7d2f5c9a1b4e6d8f0a2c4e6b8d1f" \
  -H "Propper-Workspace: acme" \
  -H "Content-Type: application/json" \
  -d '{"subject": "Moving to a 100K account", "priority": "normal"}'
```

## Response

The [ticket](/docs/api/admin/ticket), with its new `subject` and `priority`.
