| **Address**   | `https://api.hanzo.ai/v1/email/provider` |
| **Method**    | `PUT`                                    |
| **Operation** | `put_email_provider`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`   |

Sets the provider the org's mail leaves by when a send pins none:
ses or sendgrid. With none set it is SES, else SendGrid, whichever the org holds
credentials for; a send that pins one goes by it. Org admin only, and on the
audit trail (email.provider.set) before it takes effect.

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

## Examples

**CLI**

```bash
hanzo email provider
```

**SDK**

**.ts**

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

const api = new EmailApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.putEmailProvider({ provider: "<provider>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = EmailApi(client).put_email_provider(provider="<provider>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new EmailApi(client).putEmailProvider();
```

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/email/provider \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "provider": "<provider>"
     }'
```

**MCP**

MCP reaches **email** through the `email` tool, which names its 8 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_emails"
         }
       }
     }'
```
