To use Accuranker integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a generic authentication method. Once connected, you can make custom API calls to Accuranker to query the data you need using the URLs you provide, for example: to create a new record in Accuranker using n8n, you would set up the HTTP Request node with a POST method, providing the appropriate endpoint URL, headers, and body payload containing the data for the record. For updating records, utilize the PUT method and include the record's unique identifier in the URL alongside the updated data in the body. To retrieve data, you would use a GET request, specifying any necessary query parameters to filter the information you need.
