| **Address**   | `https://api.hanzo.ai/v1/iam/accounts` |
| **Method**    | `PUT`                                  |

| **Auth**      | `Authorization: Bearer $HANZO_API_KEY` |

Makes one of the accounts signed in on this browser the current
one — the account an account menu switches to — and answers the list in its new
order, current first.

Only an account ALREADY signed in here can be chosen, by the subject
GET /v1/iam/accounts named it with; anything else is refused and the order is
unchanged. Nobody is signed in or out, and nothing is granted: each account
keeps resolving to its own row, its own org and its own roles, so switching
cannot carry one account's standing to another. Like every write on the session
cookie it is taken only from this site's own pages, as JSON.

## Request

The document declares no body for `PUT /v1/iam/accounts`. 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 `put_iam_accounts`, 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 iam accounts replace
```

**SDK**

**.ts**

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

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

**.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).put_iam_accounts()
```

**.go**

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

resp, _, err := client.IamAPI.PutIamAccounts(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::put_iam_accounts(&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).putIamAccounts();
```

The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.

**HTTP**

```bash
curl -X PUT https://api.hanzo.ai/v1/iam/accounts \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **iam** through the `iam` tool, which names its 46 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"
         }
       }
     }'
```
