#### cURL

```bash
curl --request PATCH \
  --url https://api-trial.cognigy.ai/new/v2.0/flows/{flowId}/slotfillers \
  --header 'Content-Type: application/json' \
  --header 'X-API-Key: <api-key>' \
  --data '
{
  "operations": [
    {
      "op": "delete",
      "id": "<string>"
    }
  ]
}
'  
```

#### Python

```python
import requests

url = "https://api-trial.cognigy.ai/new/v2.0/flows/{flowId}/slotfillers"

payload = { "operations": [
        {
            "op": "delete",
            "id": "<string>"
        }
    ] }
headers = {
    "X-API-Key": "<api-key>",
    "Content-Type": "application/json"
}

response = requests.patch(url, json=payload, headers=headers)

print(response.text)
```

#### JavaScript (Fetch)

```javascript
const options = {
  method: 'PATCH',
  headers: {'X-API-Key': '<api-key>', 'Content-Type': 'application/json'},
  body: JSON.stringify({operations: [{op: 'delete', id: '<string>'}]})
};

fetch('https://api-trial.cognigy.ai/new/v2.0/flows/{flowId}/slotfillers', options)
  .then(res => res.json())
  .then(res => console.log(res))
  .catch(err => console.error(err));
```

#### PHP

```php
$curl = curl_init();

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
```
