FAQ

Questions about ebay_bulk_create_offer

What does the ebay_bulk_create_offer tool do? +

Bulk create up to 25 offers in one request. Each request follows the ebay_create_offer rules: FIXED_PRICE offers take pricingSummary.price and listingDuration GTC. AUCTION offers take pricingSummary.auctionStartPrice (opening bid), an optional auctionReservePrice above it, an optional pricingSummary.price as Buy It Now (at least 30% above the opening bid, and not together with Best Offer), a day-count listingDuration (DAYS_1/3/5/7/10, or DAYS_14/21/30 where the category allows; never GTC), availableQuantity omitted or 1, and no per-buyer limit or eBay Plus. Do not add listingStartDate unless the user asked for a scheduled start (it can incur a fee). Bodies that mix the two formats are rejected before any eBay request.
