A discount is a price rule: a type (flat, percent, free-shipping, free-item or bulk), a window, a scope naming the store, collection, product or variant it applies to, a target, and rules pairing a trigger — a price or quantity threshold — with an action, an amount off or a percentage. It is ENABLED BY DEFAULT, so a bare create makes a live discount rather than a draft. The rule engine caches per replica for about thirty seconds, so a discount switched off here can keep applying briefly on other replicas. Loads the stored row and decodes the body OVER it, so only the fields the body names change and everything else keeps its stored value — the difference from the full replace, which clears what it is not told. Answers the merged row. An id absent from the caller org's namespace is 404 and a body that fails to decode is 400. 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 per-kind permission table has no entry for discount, so the scaffold skips that second check with a warning and the gate above is the whole authorization story.

## Request

1 field.

| Field        | In   | Type   | Required | Description |
| ------------ | ---- | ------ | -------- | ----------- |
| `discountid` | path | string | yes      |             |

## 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 discount update <discountid>
```

**SDK**

**.ts**

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

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

**.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).patch_commerce_discount_by_discountid(discountid='discountid')
```

**.go**

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

resp, _, err := client.CommerceAPI.PatchCommerceDiscountByDiscountid(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::patch_commerce_discount_by_discountid(&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).patchCommerceDiscountByDiscountid();
```

**HTTP**

```bash
curl -X PATCH https://api.hanzo.ai/v1/commerce/discount/<discountid> \
  -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"
         }
       }
     }'
```
