      description: >-
        SignalWire Basic Authentication using Project ID and API Token.


        The client sends HTTP requests with the Authorization header containing

        the word Basic followed by a space and a base64-encoded string of
        project_id:token.

        The project ID will be used as the username and the API token as the
        password.


        Example:

        ```

        Authorization: Basic base64(project_id:token)

        ```

```

## SDK Code Examples

```python
import requests
import base64

url = "https://{your_space_name}.signalwire.com/api/relay/rest/domain_applications/id"

payload = {}
credentials = base64.b64encode(f"<project_id>:<api_token>".encode()).decode()

headers = {
    "Authorization": f"Basic {credentials}",
    "Content-Type": "application/json"
}

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

print(response.json())
```

```javascript
const url = 'https://{your_space_name}.signalwire.com/api/relay/rest/domain_applications/id';
const credentials = btoa("<project_id>:<api_token>");

const options = {
  method: 'PUT',
  headers: {
    Authorization: `Basic ${credentials}`,
    'Content-Type': 'application/json'
  },
  body: '{}'
};

try {
  const response = await fetch(url, options);
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error(error);
}
