# Set the price of a Facebook Marketplace listing

Automatically set the price of a Facebook Marketplace listing on facebook.com. Change the price of one of your own Facebook Marketplace listings, by its listing id from list_my_marketplace_listings. Only the price changes: the title and the other fields are left as they are, and the script refuses to save if the title moved. Facebook shows the old price struck through next to the new one. Returns the title, the price before and the price after as read back from the listing.
