Channel and body are required. A scheduledAt in the future makes the post "scheduled" and the durable sweep publishes it when it comes due — claimed once, so a post publishes at most once; without one it stays a draft. ## Request 10 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ------------- | ---- | --------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------- | | `body` | body | string | — | Body is the post text. | | `channel` | body | string | — | Channel is the target network: x, facebook, instagram, linkedin, tiktok, youtube or threads. | | `createdAt` | body | integer (int64) | — | CreatedAt is unix seconds when the post was added, server-assigned and never rewritten. | | `error` | body | string | — | Error is the exact reason the last publish attempt failed — the honest record behind a "failed" status, never a faked success. | | `id` | body | string | — | ID is the server-assigned post id ("cal\_" + 128 random bits). | | `publishedAt` | body | integer (int64) | — | PublishedAt is when the publish succeeded; 0 until it does. | | `scheduledAt` | body | integer (int64) | — | ScheduledAt is the unix publish time; 0 leaves the post a draft, and any value makes it "scheduled" for the durable sweep to pick up. | | `status` | body | string | — | Status is draft, scheduled, published, failed or canceled. | | `title` | body | string | — | Title is the post's internal label, capped at 1024 bytes. | | `updatedAt` | body | integer (int64) | — | UpdatedAt is unix seconds of the last write, server-assigned. | ## Response | Status | Body | Meaning | | --------- | ---------------------- | ------- | | `200` | marketing.CalendarPost | ok | | `default` | problem-details | refused | `200` body — 10 fields. | Field | In | Type | Always | Description | | ------------- | ---- | --------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------- | | `body` | body | string | — | Body is the post text. | | `channel` | body | string | — | Channel is the target network: x, facebook, instagram, linkedin, tiktok, youtube or threads. | | `createdAt` | body | integer (int64) | — | CreatedAt is unix seconds when the post was added, server-assigned and never rewritten. | | `error` | body | string | — | Error is the exact reason the last publish attempt failed — the honest record behind a "failed" status, never a faked success. | | `id` | body | string | — | ID is the server-assigned post id ("cal\_" + 128 random bits). | | `publishedAt` | body | integer (int64) | — | PublishedAt is when the publish succeeded; 0 until it does. | | `scheduledAt` | body | integer (int64) | — | ScheduledAt is the unix publish time; 0 leaves the post a draft, and any value makes it "scheduled" for the durable sweep to pick up. | | `status` | body | string | — | Status is draft, scheduled, published, failed or canceled. | | `title` | body | string | — | Title is the post's internal label, capped at 1024 bytes. | | `updatedAt` | body | integer (int64) | — | UpdatedAt is unix seconds of the last write, server-assigned. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo marketing calendar create ``` **SDK** **.ts** ```ts import { Configuration, MarketingApi } from 'hanzoai'; const api = new MarketingApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.postMarketingCalendar({ body: "", channel: "" }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import MarketingApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = MarketingApi(client).post_marketing_calendar(body="", channel="") ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.MarketingAPI.PostMarketingCalendar(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, marketing_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = marketing_api::post_marketing_calendar(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.MarketingApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new MarketingApi(client).postMarketingCalendar(); ``` **HTTP** ```bash curl -X POST https://api.hanzo.ai/v1/marketing/calendar \ -H "Authorization: Bearer $HANZO_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "body": "", "channel": "" }' ``` **MCP** MCP reaches **marketing** through the `marketing` tool, which names its 35 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_marketing_audiences" } } }' ``` --- [Marketing API](https://docs.hanzo.ai/docs/openapi/marketing) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
