To use F5 Big-IP 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 F5 Big-IP to query the data you need using the URLs you provide, for example: you can create a record in F5 Big-IP by sending a POST request to the appropriate API endpoint, including the necessary JSON payload in the body. For updating existing records, use the PUT method with the specific record ID in the URL and the updated data in the request body. To retrieve data, simply send a GET request to the desired endpoint, allowing you to access configuration information or status from F5 Big-IP.
