| `lon` | number | Yes | -180 to 180. |
| `label` | string | Yes | 1–200 characters. |

| `region` | string or null |  |  |
| `countryCode` | string or null |  |  |
| `idempotencyKey` | string | Yes | Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match. 8–200 characters. |
