To use Empsing 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 Empsing to query the data you need using the URLs you provide, for example:
for creating records in Empsing, use the HTTP Request node with a POST method and specify the endpoint for record creation.
To update records, switch the method to PATCH and provide the necessary identifiers in the URL along with the updated data in the request body.
Lastly, to retrieve data, use a GET request to the appropriate Empsing endpoint, filtering results as needed with query parameters.
