Names the browsers a session keeps — signing out the ones you leave off
while the session itself stays live. A session that does not exist is reported
as missing rather than created.

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

## Examples

**CLI**

```bash
hanzo iam sessions owner name set <owner> <name> <application>
```

**SDK**

**.ts**

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

const api = new IamApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.updateSession({ owner: 'owner', name: 'name', application: 'application', owner: "<owner>", name: "<name>", application: "<application>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = IamApi(client).update_session(owner='owner', name='name', application='application', owner="<owner>", name="<name>", application="<application>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new IamApi(client).updateSession();
```

**HTTP**

```bash
curl -X PUT https://api.hanzo.ai/v1/iam/sessions/<owner>/<name>/<application> \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "owner": "<owner>",
       "name": "<name>",
       "application": "<application>"
     }'
```

**MCP**

MCP reaches **iam** through the `iam` tool, which names its 44 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_iam_applications"
         }
       }
     }'
```
