Deprecated. This page documents the v2 buyer API, which is closed to new API clients and switches off on 1 December 2026. Use V3 instead: see Move a v2 buyer REST integration to V3. The conversion endpoint, Log event, stays open.
GET /api/v2/buyer/targeting/geo-metros Compatibility shortcut for geo metro code-name pairs. New workflows should prefer List targeting dimension values with system=nielsen_dma, and Resolve targeting dimension text when the buyer provides a name such as “LA DMA”. The optional system query parameter defaults to nielsen_dma, which is the only supported geo metro system today.

To display labels for a campaign response, request fields=geo_metro_names on list_campaigns or get_campaign; included labels return in geo_metro_names, excluded labels return in geo_metro_names_exclude, and both are derived from the same local table.
