To use Imperva WAF integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a predefined credential type. This allows you to perform custom operations, without additional authentication setup. Once connected, you can make custom API calls to Imperva WAF to query the data you need using the URLs you provide, for example: you can use the HTTP Request node to create new security policies or update existing ones by sending the appropriate JSON payloads. To retrieve data, construct GET requests to access specific logs or security events, ensuring you specify the correct endpoint and query parameters. Additionally, leveraging n8n's built-in automation capabilities, you can streamline your workflows by scheduling regular queries for insights or triggering actions based on security alerts.
