response = requests.post(url, json=firewall_config, headers=headers)
if response.status_code == 200:
return response.json()
else:
raise Exception(f"Failed to purchase firewall: {response.text}")
# Example usage
api_key = "your_api_key_here"
firewall_config = {
"name": "MyFirewall",
"type": "NGFW",
"rules": [
{"action": "allow", "protocol": "TCP", "port": 80},
{"action": "deny", "protocol": "UDP", "port": 53}
],
"region": "us-west-2"
}
try:
