It removes the channel from the PLAN. A channel that is live at its provider should be paused first — dropping the row here leaves nothing to pause it with afterwards. ## Request 2 fields. | Field | In | Type | Required | Description | | ------ | ---- | ------ | -------- | ------------------------------------------------------ | | `id` | path | string | yes | ID is the campaign, from the path. | | `kind` | path | string | yes | Kind is the channel to remove: paid, organic or email. | ## Response | Status | Body | Meaning | | --------- | ----------------------- | ------- | | `200` | campaign.campaignRecord | ok | | `default` | problem-details | refused | `200` body — 16 fields. | Field | In | Type | Always | Description | | ----------------------- | ---- | ----------------------- | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `audience` | body | string | — | Audience is an opaque reference to the segment this campaign targets. | | `budget` | body | integer (int64) | — | Budget is the campaign's total budget in CENTS, handed to each executor as the budget for its channel. | | `channels` | body | campaign.ChannelSpec\[] | — | Channels are the fan-out targets, at most one per kind and at most 12, each carrying its own post-launch state. | | `channels[].account` | body | string | — | Account is the provider account this channel runs under: an ad-account, a page or a mailing-list id. | | `channels[].detail` | body | string | — | Detail is the last outcome in one secret-free line — the failure reason, or what the executor reported. | | `channels[].externalId` | body | string | — | ExternalID is the provider-side id of the running execution, recorded by the orchestrator at launch and handed back verbatim to read spend or to pause. | | `channels[].kind` | body | string | — | Kind is the channel and the identity a campaign holds at most one of: paid, organic or email. | | `channels[].platform` | body | string | — | Platform is the provider within the kind — meta, google, x, instagram, or the email provider. | | `channels[].status` | body | string | — | Status is this channel's own launch outcome, not the campaign's: pending (added, never launched), live, paused, failed (Detail says why) or unavailable (no executor wired on this deployment). | | `content` | body | string\[] | — | Content is the ordered creative set, at most 32, empty entries dropped. | | `createdAt` | body | integer (int64) | — | CreatedAt is when the campaign was created, in unix seconds. | | `id` | body | string | — | ID is the campaign's server-minted handle — "cmp\_" and 128 random bits — and the id every other campaign call is addressed by. | | `name` | body | string | — | Name is the campaign's display name. | | `scheduleAt` | body | integer (int64) | — | ScheduleAt is when the campaign should run, in unix seconds. | | `status` | body | string | — | Status is the lifecycle state, server-owned and never accepted from a caller. | | `updatedAt` | body | integer (int64) | — | UpdatedAt is the last write in unix seconds — an edit, a launch or a pause. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo campaign channels rm ``` **SDK** **.ts** ```ts import { Configuration, CampaignApi } from 'hanzoai'; const api = new CampaignApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.deleteCampaignByIdChannelsByKind({ id: 'id', kind: 'kind' }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import CampaignApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = CampaignApi(client).delete_campaign_by_id_channels_by_kind(id='id', kind='kind') ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.CampaignAPI.DeleteCampaignByIdChannelsByKind(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, campaign_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = campaign_api::delete_campaign_by_id_channels_by_kind(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.CampaignApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new CampaignApi(client).deleteCampaignByIdChannelsByKind(); ``` **HTTP** ```bash curl -X DELETE https://api.hanzo.ai/v1/campaign//channels/ \ -H "Authorization: Bearer $HANZO_API_KEY" ``` **MCP** MCP reaches **campaign** through the `campaign` tool, which names its 9 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them: ```bash curl -X POST https://api.hanzo.ai/v1/mcp \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "describe", "arguments": { "op": "list_campaigns" } } }' ``` --- [Campaign API](https://docs.hanzo.ai/docs/openapi/campaign) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
