A collection is a merchandising group a storefront renders — a slug and name, copy and media, flat lists of the product and variant ids it holds, published, preorder and out-of-stock flags, and an availability window. Membership lives on the collection as those id lists rather than as a join, so putting a product into a collection is a write here and not on the product. Decodes the body into a new row in the caller org's own namespaced store — isolated to that tenant from its first write — and answers the stored row at 201 with a Location header naming its id. The id is assigned by the store, not taken from the body. A body that fails to decode is 400 and a store that refuses the write is 500. Any valid access token reaches it. The org must also be entitled to the commerce admin: the paywall answers 402 subscription\_required unless the org holds an active or trialing pro subscription, a live trial credit or a redeemed invite, and 503 when that entitlement cannot be read rather than admitting on an unknown. A platform superadmin passes straight through. The token must also carry Admin or WriteCollection.

## Request

The document declares no body for `POST /v1/commerce/collection`. The handler is typed in cloud but its shape is not yet emitted, so the fields are not listed here — ask MCP's `describe` for `post_commerce_collection`, which answers from the running route.

## Response

The document declares no response body for this operation. It answers `200` on success and the platform error shape on failure — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo commerce collection create
```

**SDK**

**.ts**

```ts
import { Configuration, CommerceApi } from 'hanzoai';

const api = new CommerceApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postCommerceCollection();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import CommerceApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = CommerceApi(client).post_commerce_collection()
```

**.go**

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

resp, _, err := client.CommerceAPI.PostCommerceCollection(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, commerce_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = commerce_api::post_commerce_collection(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.CommerceApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new CommerceApi(client).postCommerceCollection();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/commerce/collection \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **commerce** through the `commerce` tool, which names its 5 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": "get_commerce_health"
         }
       }
     }'
```
