To use Kibana 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 Kibana to query the data you need using the URLs you provide, for example: you can use the HTTP Request node to create records in Kibana by sending a POST request to the appropriate API endpoint with the necessary JSON payload. For updating records, a PATCH request can be used, specifying the document ID and the fields you wish to modify. To retrieve data, use a GET request with query parameters that align with your Kibana data structure, allowing you to filter the results as needed.
