| **Address**   | `https://api.hanzo.ai/v1/captable/stakeholders/{id}` |
| **Method**    | `PATCH`                                              |
| **Operation** | `patch_captable_stakeholders_by_id`                  |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`               |

Changes one of the caller org's stakeholders. It is a
PARTIAL update: only the fields the request names are written, and a field
sent as null clears that column. A request that names no updatable field is
refused, and an id this org does not hold is not found.

The values are stored as sent. Unlike adding a stakeholder, this route does
not check the email's shape or the type and relationship vocabularies, so it
can record a value that adding one would have rejected.

## Request

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

| Field                 | In   | Type   | Required | Description                                                                                            |

`200` body — 2 fields.

| Field     | In   | Type    | Always | Description                                                                |

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

## Examples

**CLI**

```bash
hanzo captable stakeholders update <id>
```

**SDK**

**.ts**

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

const api = new CaptableApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.patchCaptableStakeholdersById({ id: 'id', city: "<city>", currentRelationship: "<currentRelationship>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = CaptableApi(client).patch_captable_stakeholders_by_id(id='id', city="<city>", current_relationship="<currentRelationship>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new CaptableApi(client).patchCaptableStakeholdersById();
```

**HTTP**

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

**MCP**

MCP reaches **captable** through the `captable` tool, which names its 30 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_captable_classes"
         }
       }
     }'
```
