sendOfferToInterestedBuyers: eBay Negotiation API

POST/send_offer_to_interested_buyers

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.

Request fields

Input container/field	Type	Description
allowCounterOffer	boolean	If set to `true`, the buyer is allowed to make a counter-offer to the seller's offer. Note: Currently, you must set this field to `false`; counter-offers are not supported in this release. Default: `false` Occurrence: Optional
message	string	A seller-defined message related to the offer being made. This message is sent to the list of "interested" buyers. To increase the conversion rate of the offers a seller makes to buyers, eBay recommends you always add a customized message to your offers. Maximum length: 2,000 characters Occurrence: Optional
offerDuration	TimeDuration	The length of time the offer is valid from when it is created. The duration of the offer begins at the date and time denoted by creationDate. When the span of time specified by offerDuration passes beyond the creationDate, the offer expires. Note: offerDuration currently defaults to 2 days and you cannot set it to any other value (if specified, the unit and value fields in TimeDuration must be set to `DAY` and `2`, respectively). Default: 2 Days Occurrence: Optional
offerDuration.unit	TimeDurationUnitEnum	A time-measurement unit that specifies a singular period of time. A span of time is defined when you apply the value specified in the value field to the value specified for unit. Time-measurement units can be YEAR, MONTH, DAY, and so on. See TimeDurationUnitEnum for a complete list of possible time-measurement units. Occurrence: Required
offerDuration.value	integer	An integer that represents an amount of time, as measured by the time-measurement unit specified in the unit field. Occurrence: Required
offeredItems	array of OfferedItem	An array of objects where each object contains the details of an offer and the ID of the listing on which the offer is being made. Note that the service does not currently support the creation of multiple offers with a single call to sendOfferToInterestedBuyer. With this, each request can target only one listing at a time and you must populate this array with a single element that contains the details of one offer. Occurrence: Required
offeredItems.discountPercentage	string	This value denotes the percentage that the listing in the offer will be discounted from its original listed price. The seller can specify either the exact price of the discounted items with the price field or they can use this field to specify the percentage that the listing will be discounted, but not both. Minimum: `5` Required if you do not specify a price value. Occurrence: Conditional
offeredItems.listingId	string	This value is a unique eBay-assigned ID that identifies the listing to which the offer pertains. A listingId value is generated by eBay when you list an item with the Trading API. Occurrence: Required
offeredItems.price	Amount	This value denotes the final discounted price of the listing in the offer being made to the buyer. This value must be lower than the original price of the item as stated in the original listing. The seller can use either this field to specify the exact discounted price of the listing or they can use the discountPercentage field to specify the percentage that the listing will be discounted, but not both. Required if you do not specify a discountPercentage value. Occurrence: Conditional
offeredItems.price.currency	CurrencyCodeEnum	The base currency applied to the value field to establish a monetary amount. The currency is represented as a 3-letter ISO4217 currency code. For example, the code for the Canadian Dollar is `CAD`. Default: The default currency of the eBay marketplace that hosts the listing. Occurrence: Optional
offeredItems.price.value	string	The monetary amount in the specified currency. Occurrence: Required
offeredItems.quantity	integer	This integer value indicates the number of items in the eBay listing for which the offer is being made. The offer being made by the seller is an "all or nothing" offer, meaning the buyer must purchase the indicated quantity of items in order to receive the discount on the transaction. Default: `1` Occurrence: Optional
