To use Spydra 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 Spydra to query the data you need using the URLs you provide, for example: to retrieve data from Spydra, configure your HTTP Request node with a GET method, specifying the desired endpoint, and parse the response to extract the information. For creating records, switch to a POST method and include the necessary data payload in the body, ensuring it adheres to Spydra's API specifications. To update records, utilize the PATCH method, including the record ID in the URL and the data you wish to modify in the request body.
