eBay listings, inventory, offers, and orders are useful when they can be reviewed together around the SKU—not in separate Seller Hub screens and reports. The seller grants an app access through eBay's OAuth screen. The underlying listing model still matters: the inventory item holds product and quantity, the offer holds price, and publishing the offer creates the live listing.
The seller grants an authorization-code OAuth token. The consent screen is eBay's. A read uses the readonly scope where one exists. A write uses the scope without readonly. Inventory and offer writes send a Content-Language header.
The seller's consent is the grant. The seller still finishes registration in eBay, and managed payments onboarding is finished outside the API call.
The SKU, the quantity, the offer price, the live listing once the offer is published, the order, the payout, and the fees. A fee call before publish is an estimate. It does not publish the listing.
The inventory item, the offer, business policies, shipment tracking, a promotion, and a Promoted Listings campaign. Publishing the offer is what creates the listing. People who search for an eBay AI listing tool are often looking for a button inside Seller Hub. This path is the Sell API, which an outside app calls after the seller grants access.
A refund moves money. This guide does not treat a refund as an AI write. A price change and a Promoted Listings campaign should wait for a person before they go live. No official eBay MCP server is part of this connection.
Review eBay listing, price, and inventory information alongside relevant product details from your other channels.
See last month's revenue and its change with the rest of the channel picture, rather than treating each marketplace report as a separate answer.
Decide who reviews a proposed launch, price, or stock change and how it is handled in your eBay workflow. Supported actions depend on your account access and agreed scope.
The seller grants access with eBay's OAuth consent screen. The app then calls the Sell APIs with that token.
It writes the inventory item and the offer, then publishes the offer. That publish is what creates the listing. This is separate from tools inside Seller Hub.
The inventory item holds the product and the quantity. The offer holds the marketplace price and the policies. One SKU can have more than one offer.
Yes. The fee call returns an estimate and does not publish the listing.
No. A refund moves money, and this guide does not walk through it. A price or a Promoted Listings change should wait for a person.
