# Replace campaigns URL: https://docs.hanzo.ai/docs/openapi/ad/put-ad-campaigns-by-id > Replaces the user-owned fields of one of the caller org's campaigns and answers the stored row. `PUT /v1/ad/campaigns/{id}` > [Ad →](https://docs.hanzo.ai/docs/openapi/ad) · [All API references →](https://docs.hanzo.ai/docs/openapi) · [Get started →](https://docs.hanzo.ai/docs/guides) | | | | ------------- | ------------------------------------------- | | **Address** | `https://api.hanzo.ai/v1/ad/campaigns/{id}` | | **Method** | `PUT` | | **Operation** | `put_ad_campaigns_by_id` | | **Auth** | `Authorization: Bearer $HANZO_API_KEY` | Replaces the user-owned fields of one of the caller org's campaigns and answers the stored row. It is a full replace, not a patch: every field is written from the request, so an omitted one is cleared. externalId is launch-owned and is never touched here, so editing a campaign cannot break its link to a live provider execution. ## Request 8 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ----------- | ---- | --------------- | -------- | --------------------------------------------------------------------------- | | `id` | path | string | yes | | | `account` | body | string | — | Account is the provider ad-account this campaign runs on (Meta act\_\). | | `budget` | body | integer (int64) | — | Budget is the campaign budget in MINOR units (cents). | | `name` | body | string | — | Name is the campaign's display label. | | `objective` | body | string | — | Objective is the campaign goal as the provider names it. | | `platform` | body | string | — | Platform is the ad network: meta, google, tiktok or x. | | `spend` | body | integer (int64) | — | Spend is the amount spent so far in MINOR units (cents). | | `status` | body | string | — | Status is the lifecycle state: draft, active, paused or completed. | ## Response | Status | Body | Meaning | | --------- | --------------- | ------- | | `200` | ad.AdCampaign | ok | | `default` | problem-details | refused | `200` body — 11 fields. | Field | In | Type | Always | Description | | ------------ | ---- | --------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `account` | body | string | — | Account is the provider ad-account the campaign runs under, in Meta's act\_\ form. | | `budget` | body | integer (int64) | — | Budget is the campaign's authorized spend in MINOR units (cents). | | `createdAt` | body | integer (int64) | — | CreatedAt is when the campaign was first stored, in unix seconds. | | `externalId` | body | string | — | ExternalID is the ad network's own campaign id, written by a successful launch and by nothing else — an update never touches it. | | `id` | body | string | — | ID is the campaign's server-minted handle, "camp\_" + 32 hex. | | `name` | body | string | — | Name is the campaign's display label, and the name Meta creates the campaign object under at launch. | | `objective` | body | string | — | Objective is the campaign goal spelled as the provider names it ("conversions", "OUTCOME\_TRAFFIC"), passed through to the network verbatim at launch — Meta defaults an empty one to OUTCOME\_TRAFFIC. | | `platform` | body | string | — | Platform is the ad network: meta, google, tiktok or x, and nothing else — a write naming another is 400. | | `spend` | body | integer (int64) | — | Spend is spend-to-date in MINOR units (cents), as last written through create or update. | | `status` | body | string | — | Status is the lifecycle: draft, active, paused or completed, and nothing else — a write naming another is 400. | | `updatedAt` | body | integer (int64) | — | UpdatedAt is when the row was last written, in unix seconds — set by create, update and launch. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo ad campaigns set ``` **SDK** **.ts** ```ts import { Configuration, AdApi } from 'hanzoai'; const api = new AdApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.putAdCampaignsById({ id: 'id', account: "", budget: 0 }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import AdApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = AdApi(client).put_ad_campaigns_by_id(id='id', account="", budget=0) ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.AdAPI.PutAdCampaignsById(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, ad_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = ad_api::put_ad_campaigns_by_id(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient;
