Sell on eBay from the
catalogue you already run.
Connect your own eBay account and list straight from your CARTT.AI catalogue. Listings, inventory, prices, orders, fulfilments and feedback sync two ways from one stock pool — native and guarded, not no-code glue. A built-in feedback-loop guard keeps the two sides from arguing. Available on the Network tier.
A live channel, not a one-time upload.
Connected over OAuth to the eBay Sell APIs, the integration keeps both sides current — per portal, from the same catalogue. List once and your eBay store reflects what's true in CARTT.AI, while sales and feedback flow back the other way.
A guard that stops inventory ping-pong.
Two systems syncing the same stock can fall into a loop — an update on one side bounces back as a fresh change on the other, and the numbers never settle. The feedback-loop guard recognises a change that came from the other side and refuses to echo it, so CARTT.AI and eBay stay in agreement instead of arguing.
- Changes that originate elsewhere aren't bounced straight back
- HMAC-signed notification reconciliation keeps both sides honest
- Stock settles to one true number, not a tug-of-war
- One stock pool means eBay and your store never oversell each other
Listings that fit eBay's rules.
eBay wants the right category, the right item aspects, and a postage, payment and returns policy on every listing. Category and aspect mapping shapes your products to those requirements, and your default business policies apply as listings go up — so you're not rebuilding each item field by field to satisfy the marketplace.
- Category mapping places products in the right eBay category
- Aspect mapping fills the item specifics eBay asks for
- Default business policies apply postage, payment and returns
- Connected per portal, so each storefront lists on its own terms
Built into the platform, not bolted on.
This isn't a no-code connector sitting between your store and eBay. It's part of the platform — your own eBay account, connected over OAuth, syncing both ways with reconciliation that keeps the two sides agreeing.
Your account, over OAuth
You connect your own eBay account per portal — your listings, your selling history, your reputation. CARTT.AI never lists on someone else's account.
Two-way Sell API sync
Listings, inventory, prices, orders, fulfilments and feedback move both ways through the eBay Sell APIs — not a nightly one-shot push.
Signed reconciliation
HMAC-signed notification reconciliation verifies what eBay reports before it acts, so the two sides reconcile to the truth rather than to noise.
Where eBay fits in the bigger picture.
Selling on eBay is one channel off one catalogue. Here's what sits around it — explore the parts that match how you operate.
