# Authenticate and obtain a session token
response = requests.post(f'nessus_url/session', auth=(api_key, ''))
session_token = response.json()['token']
# Initiate a scan
scan_data =
'scan_name': 'My Example Scan',
'target': target_ip,
'scan_type': 'full'
response = requests.post(f'nessus_url/scans', json=scan_data, headers='X-Cookie': f'session=session_token')
# Get the scan ID and monitor progress
scan_id = response.json()['id']
while True:
response = requests.get(f'nessus_url/scans/scan_id', headers='X-Cookie': f'session=session_token')
scan_status = response.json()['status']
if scan_status == 'completed':
break
# ... monitor progress and handle errors ...

response = requests.get(f'nessus_url/scans/scan_id/results', headers='X-Cookie': f'session=session_token')
