Inventory API Version 1.18.4

Starting July 15, eBay requires Parts & Accessories sellers to offer free returns for 30 days or longer on US domestic shipping, with a 50% discount on return shipping labels. For more details, visit Seller Updates page. For support, visit support related to easy returns in P&A.

Initially, eBay will automatically update return policy settings as applicable and return a warning, but beginning in late August, eBay will start blocking listing creation and revisions through API calls with an error. The following warning and error messages were added to the bulkCreateOrReplaceInventoryItem, createOrReplaceInventoryItem, createOrReplaceProductCompatibility, createOrReplaceInventoryItemGroup, bulkPublishOffer, publishOffer, publishOfferByInventoryItemGroup, and updateOffer methods:

Error code: 25123: This P&A listing has a non-compliant domestic return policy. Please update the return window to 30-days (or more) and/or update return shipping cost payer to Seller, and then make another call. Sellers using business policies must make the same changes to their return business policy and then make another call.

Error code: 25124: This P&A listing requires a minimum 30-day return period and seller-paid return shipping. eBay automatically updated the listing's return policy settings to meet these requirements.
