Creates a group on the org's WhatsApp number and returns
its invite link.

Org admin, because the group speaks as the org's number and the invite link
admits anyone who holds it.

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

## Examples

**CLI**

```bash
hanzo provider whatsapp groups create
```

**SDK**

**.ts**

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

const api = new ProviderApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postProviderWhatsappGroups({ description: "<description>", subject: "<subject>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = ProviderApi(client).post_provider_whatsapp_groups(description="<description>", subject="<subject>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new ProviderApi(client).postProviderWhatsappGroups();
```

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 POST https://api.hanzo.ai/v1/provider/whatsapp/groups \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "description": "<description>",
       "subject": "<subject>"
     }'
```

**MCP**

MCP reaches **provider** through the `provider` tool, which names its 41 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_connections"
         }
       }
     }'
```
