To use Evolphin Zoom 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 Evolphin Zoom to query the data you need using the URLs you provide, for example: after setting up the connection, you can use the HTTP Request node to create, update, or retrieve records from Evolphin Zoom. For instance, to create a new record, send a POST request to the appropriate endpoint with the required data in the payload. To retrieve specific data, you can utilize a GET request with URL parameters to filter the results based on your criteria.
