Get product information

Do you have a WordPress function i can use to get product information by postid? Let me explain why: I am trying to create a custom email notification to my vendors/sellers when they post an item for sale, but I want to include a description of the item in the email notification. They will create products in eShop, then attach them to a post with more information and maybe ads. I can hook into the ‘publish_post’ action but i’m not sure how to get the eShop product information attached to that post.
