| **Method**    | `POST`                                        |

Registers a drip sequence in the caller's org. Name is
required; status defaults to draft, and a sequence must be ACTIVE before it
will accept enrollments. The id, createdAt and updatedAt of the input are
ignored — the server assigns them.

## Request

5 fields, body `application/json` (required).

| Field       | In   | Type            | Required | Description                                                                                                                     |
| ----------- | ---- | --------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------- |
| `createdAt` | body | integer (int64) | —        | CreatedAt is unix seconds when the sequence was registered, server-assigned and never rewritten.                                |
| `id`        | body | string          | —        | ID is the server-assigned sequence id ("seq\_" + 128 random bits).                                                              |
| `name`      | body | string          | —        | Name is the sequence's label.                                                                                                   |
| `status`    | body | string          | —        | Status is the lifecycle: draft, active or archived.                                                                             |
| `updatedAt` | body | integer (int64) | —        | UpdatedAt is unix seconds of the last status flip, server-assigned, and the key the sequence list is ordered by (newest first). |

## Response

| Status    | Body               | Meaning |
| --------- | ------------------ | ------- |
| `200`     | marketing.Sequence | ok      |
| `default` | problem-details    | refused |

`200` body — 5 fields.

| Field       | In   | Type            | Always | Description                                                                                                                     |
| ----------- | ---- | --------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------- |
| `createdAt` | body | integer (int64) | —      | CreatedAt is unix seconds when the sequence was registered, server-assigned and never rewritten.                                |
| `id`        | body | string          | —      | ID is the server-assigned sequence id ("seq\_" + 128 random bits).                                                              |
| `name`      | body | string          | —      | Name is the sequence's label.                                                                                                   |
| `status`    | body | string          | —      | Status is the lifecycle: draft, active or archived.                                                                             |
| `updatedAt` | body | integer (int64) | —      | UpdatedAt is unix seconds of the last status flip, server-assigned, and the key the sequence list is ordered by (newest first). |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo marketing sequences 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.postMarketingSequences({ createdAt: 0, id: "<id>" });
```

**.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_sequences(created_at=0, id="<id>")
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.MarketingAPI.PostMarketingSequences(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_sequences(&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).postMarketingSequences();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/marketing/sequences \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "createdAt": 0,
       "id": "<id>"
     }'
```

**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"
         }
       }
     }'
```
