For product feed configuration, there are some params that can be configured on the module:
- add_vat, default off (off/on) -> add vat to product price
- vat_value, default 19% -> vat value to be added. Must be set as 19 for 19% or 25 for 25%
- taxes, default on (off/on) -> add taxes to product prices
- specialprice, default off (off/on) -> considers specialprice always instead of validating special price validity period
- availability, default on (off/on) -> return availability for items
- on_stock, default on (off/on) -> only return on stock products
- get_stock, default off (off/on) -> return stock for products
- final_price, default off (off/on) -> return final price on products
You will need to add those values to your feed URL section in Setup -> Feed, if the values you are looking for are different from our defaults.
For example if the feed URL is: https://example.com/feed.php you will end up having it like: https://example.com/feed.php?on_stock=off&combinations=on
