WC_API_Orders::get_variation_id( WC_Product $product, array $variations = array() )
Given a product ID & API provided variations, find the correct variation ID to use for calculation We can’t just trust input from the API to pass a variation_id manually, otherwise you could pass the cheapest variation ID but provide other information so we have to look up the variation ID.
