| Name | Type | Description | Notes |
|---|---|---|---|
| key | String | Meta city ID, from /v1/ads/targeting/search results. | |
| radius | BigDecimal | Optional radius around the city. Must be set together with distance_unit. Meta enforces a minimum city radius (~17 km / 10 mi); smaller values resolve to a 0-size audience and the ad fails at launch. For a tighter catchment use customLocations (lat/lng). | [optional] |
| distanceUnit | DistanceUnitEnum | Unit for radius. Required if radius is set. | [optional] |
| Name | Value |
