  const resp = await fetch(`${apiBaseUrl}/link`, {
    method: 'DELETE',
    headers: {
      'Authorization': `Bearer ${apiToken}`,

    const err = await resp.json().catch(() => ({}));
    throw new Error(`Link delete failed: ${resp.status} ${err.error || ''}`);
  }

  return resp.json();
}

// usage
deleteLink('https://synaptask.space/api', '<YOUR_API_TOKEN>', 'link-uuid')
  .then(data => console.log('Deleted link diff:', data.diff))
  .catch(console.error);

Example (Python)

import requests

    except Exception:
        err = {}
    raise RuntimeError(f"Link delete failed: {resp.status_code} {err}")
