This method sends eligible buyers offers to purchase items in a listing at a discount. When a buyer has shown interest in a listing, they become "eligible" to receive a seller-initiated offer to purchase the item(s). Sellers use findEligibleItems to get the set of listings that have interested buyers. If a listing has interested buyers, sellers can use this method (sendOfferToInterestedBuyers) to send an offer to the buyers who are interested in the listing. The offer gives buyers the ability to purchase the associated listings at a discounted price. For details about how to create seller offers to buyers, see Sending offers to buyers.
