When using woocomemrce node to get a product or many products, all the product’s fields are returned.
There are cases that you want only specific fields from the products, like get only the name and sku etc.
Via HTTP node API call you can define it like this
The _fields parameter definies what fields should be returned and not all the product’s data.
It would be good for the woocommerce node to have this option so you can define what fields are returned and not fetching everything that leads to slower fetch times especially if you have many products.
