To use Radar 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 Radar to query the data you need using the URLs you provide, for example: for example, you can use the HTTP Request node to create a new record in Radar by making a POST request to the appropriate endpoint, supplying the necessary data in the body. Similarly, if you need to update existing records, you can use a PUT request, specifying the record ID in the URL. To retrieve data, simply perform a GET request to the desired endpoint and process the returned results as needed.
