WooCommerce API x Bubble Integration Very Slow

Hi,
my app fetches orders via WooCommerce API and stores them in the Order dataset. The API returns a lot of parameters, but we only use a few selected ones - let’s assume only ‘ID’, ‘total’ and ‘created_date’. However, orders are uploaded to the database very, very slowly - 100 orders in about 3 minutes. And I don’t know why it works so slowly - calling the API, parsing parameters, saving to the database?
I will try to show in the screenshots below how it goes. I’m using a workklow backend that creates new Order items from the response returned by the API.
How to ‘speed it up’?
