To use Retable 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 Retable to query the data you need using the URLs you provide, for example: for example, to create a new record in Retable, you would send a POST request to the appropriate endpoint with the relevant data in the body. If you want to update an existing record, use the PATCH method and specify the record ID in the URL along with the updated data. To retrieve data, simply make a GET request, using query parameters to filter the results as needed.
