| ------------- | ----------------------------------------- |
| **Address**   | `https://api.hanzo.ai/v1/auto/flows/{id}` |
| **Method**    | `PATCH`                                   |
| **Operation** | `patch_auto_flows_by_id`                  |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`    |

Updates one automation's metadata in place. Every field is optional; a
field the request omits is left alone. Publishing a version pins which one runs,
and is refused unless that version belongs to this flow.

## Request

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

| Field                | In   | Type   | Required | Description                                        |
| -------------------- | ---- | ------ | -------- | -------------------------------------------------- |
| `id`                 | path | string | yes      | ID is the flow to update, from the path.           |
| `externalId`         | body | string | —        | ExternalID sets the caller's own id for this flow. |
| `folderId`           | body | string | —        | FolderID moves the flow in the builder's tree.     |
| `id`                 | body | string | —        | ID is the flow to update, from the path.           |
| `metadata`           | body | any    | —        | Metadata replaces the caller's opaque JSON.        |
| `publishedVersionId` | body | string | —        | PublishedVersionID pins the version runs execute.  |

## Response

| Status    | Body            | Meaning |
| --------- | --------------- | ------- |
| `200`     | auto.Flow       | ok      |
| `default` | problem-details | refused |

`200` body — 9 fields.

| Field                | In   | Type            | Always | Description                       |

| `created`            | body | integer (int64) | —      |                                   |
| `externalId`         | body | string          | —      |                                   |
| `folderId`           | body | string          | —      |                                   |
| `id`                 | body | string          | —      |                                   |
| `metadata`           | body | any             | —      |                                   |
| `projectId`          | body | string          | —      | projectId == org (server-derived) |
| `publishedVersionId` | body | string          | —      |                                   |
| `status`             | body | string          | —      |                                   |

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

## Examples

**CLI**

```bash
hanzo auto flows update <id>
```

**SDK**

**.ts**

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

const api = new AutoApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.patchAutoFlowsById({ id: 'id', externalId: "<externalId>", folderId: "<folderId>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = AutoApi(client).patch_auto_flows_by_id(id='id', external_id="<externalId>", folder_id="<folderId>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new AutoApi(client).patchAutoFlowsById();
```

**HTTP**

```bash
curl -X PATCH https://api.hanzo.ai/v1/auto/flows/<id> \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "externalId": "<externalId>",
       "folderId": "<folderId>"
     }'
```

**MCP**

MCP reaches **auto** through the `auto` tool, which names its 14 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_auto_flows"
         }
       }
     }'
```
