--- title: "Update an audience" method: PUT path: "/v1/ads/audiences/{audienceId}" tags: ["Ad Audiences"] --- # Update an audience `PUT /v1/ads/audiences/{audienceId}` Update an audience. `saved_targeting` audiences accept `name`, `description`, and `spec` (full replacement, no merge, Zernio-only, no platform call). Platform audiences (uploaded/website/lookalike) accept `name` and `description` only, updated on the platform first and then mirrored locally; their rules are immutable, so `spec` returns 400 for them. Platform audience updates are Meta-only for now (other platforms return 501). Ads already created from a saved_targeting audience are unaffected, they snapshot the targeting at creation. ## Path parameters - `audienceId` string, required ## Request body - object — At least one field is required. - `name` string - `description` string - `spec` TargetingSpec — Normalized, platform-agnostic ad-targeting spec. Every field is optional, an empty object targets the platform's default broadest audience. Field names are camelCase and identical across `POST /v1/ads/create` (the `targeting` object), `POST /v1/ads/targeting/reach-estimate`, and `saved_targeting` audiences, so a spec resolved once can be reused verbatim. Entity ids (`regions[].key`, `cities[].key`, `zips[].key`, `metros[].key`, `interests[].id`, `behaviors[].id`) are the platform's opaque identifiers resolved via `GET /v1/ads/targeting/search`. A spec is therefore meaningful only for the platform it was built against, except the portable fields (`countries`, `ageMin`/`ageMax`, `gender`, `incomeTier`, `languages`) which carry across platforms. Fields a platform cannot honour are rejected at create time with `INVALID_FIELD_VALUE` naming the offending field (not silently dropped). - `countries` string[] — ISO 3166-1 alpha-2 country codes (e.g. ['US']). - `regions` object[] — Region/state targeting. `key` is the platform location ID from /v1/ads/targeting/search?dimension=geo&geoType=region. - `key` string, required - `name` string - `cities` object[] — City targeting. Optional `radius` + `distanceUnit` extend beyond the city limits; both must be set together or both omitted. `radius` is only honoured on platforms whose capability map allows city radius (Meta). - `key` string, required - `name` string - `radius` number — Radius around the city. Requires distanceUnit. 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), which allows a smaller radius. - `distanceUnit` 'mile' | 'kilometer' — Required if radius is set. - `zips` object[] — Postal/ZIP targeting. `key` is the platform's postal location ID (e.g. Meta `US:94304`). Supported on Meta, Google, TikTok, Pinterest, X. - `key` string, required - `name` string - `metros` object[] — DMA / metro-area targeting. `key` is the platform's metro ID (e.g. Meta `DMA:807`). - `key` string, required - `name` string - `customLocations` object[] — Point-radius (lat/lng) targeting (Meta custom_locations / Google proximity). Honoured only where the capability map allows radius (Meta). - `latitude` number, required - `longitude` number, required - `radius` number, required — Positive radius around the point. - `distanceUnit` 'mile' | 'kilometer', required - `name` string - `address` string — Optional label, sent to Meta as `address_string`. latitude/longitude take precedence for the pin location. - `excludedLocations` object — Geo to exclude from the audience. Mirrors the inclusion geo shape: excluded cities can carry a radius catchment and excluded custom (lat/lng) pins are supported, both on Meta (excluded_geo_locations). - `countries` string[] - `regions` object[] - `key` string, required - `name` string - `cities` object[] — Cities to exclude. Optional `radius` + `distanceUnit` exclude a catchment around the city (both must be set together or both omitted); Meta honours the radius on excluded cities. - `key` string, required - `radius` number — Radius around the excluded city. Requires distanceUnit. - `distanceUnit` 'mile' | 'kilometer' — Required if radius is set. - `zips` object[] - `key` string, required - `name` string - `places` object[] — Named points of interest to exclude. `key` from /v1/ads/targeting/search. - `key` string, required - `neighborhoods` object[] — Named neighbourhood areas to exclude. `key` from /v1/ads/targeting/search. - `key` string, required - `customLocations` object[] — Point-radius (lat/lng) pins to exclude (Meta excluded_geo_locations.custom_locations). Mirrors the inclusion customLocations shape. - `latitude` number, required - `longitude` number, required - `radius` number, required — Positive radius around the point. - `distanceUnit` 'mile' | 'kilometer', required - `name` string - `address` string — Optional label, sent to Meta as `address_string`. latitude/longitude take precedence for the pin location. - `ageMin` integer - `ageMax` integer - `gender` 'all' | 'male' | 'female' — Restrict by gender. 'all' (default) targets everyone. Applied on Meta, TikTok and Pinterest. Ignored on Google, LinkedIn and X. - `incomeTier` 'top_5' | 'top_10' | 'top_10_25' | 'top_25_50' — Normalized household-income tier (ZIP/percentile based). Meta and TikTok express all four. Google maps only `top_10` (its INCOME_RANGE_90_UP); other tiers on Google, and any income tier on LinkedIn / X / Pinterest, are rejected. On Meta, income/zip targeting requires the relevant `specialAdCategories` to be unset (housing/employment/credit ads cannot use it). - `languages` string[] — Language codes restricting the audience by language. On Meta, ISO 639-1 codes (e.g. ['en']); a bare code targets all regional variants ("en" = all English), or use a region-qualified code ("en_GB", "pt_BR") for a specific one. Unknown codes are rejected. - `interests` object[] — Interest entities from /v1/ads/targeting/search?dimension=interest. Each carries the platform's opaque id. - `id` string, required - `name` string - `behaviors` object[] — Behaviour entities from /v1/ads/targeting/search?dimension=behavior. Supported on Meta and TikTok. - `id` string, required - `name` string - `industries` string[] — LinkedIn B2B only. Industry URN id fragments. - `companySizes` string[] — LinkedIn B2B only. - `seniorities` string[] — LinkedIn B2B only. - `jobFunctions` string[] — LinkedIn B2B only. - `audienceInclude` string[] — Platform audience IDs to include. - `audienceExclude` string[] — Platform audience IDs to exclude. ## Response `200` Audience updated - object - `audience` object - `message` string ## Other responses - `400` — Invalid body (no fields provided, malformed spec, or spec on a platform audience) - `401` — Unauthorized - `403` — Ads access required. Legacy plans need the Ads add-on; included by default on usage-based plans. - `404` — Resource not found - `422` — The audience has no platform counterpart to update - `501` — Platform audience updates are only supported on Meta --- [API](https://skmtc.net/zernio/apis/zernio-api.md) · [All operations](https://skmtc.net/zernio/apis/zernio-api/llms.txt) · [OpenAPI document](https://skmtc-service-staging.skmtc.workers.dev/v1/apis/zernio/zernio-api/versions/51932b099b2f/schema)
