Connect eBay to Ordovee — the full sync setup

You sell on eBay, and today every sale means logging into eBay to adjust a quantity by hand. This walkthrough connects your eBay account to Ordovee so orders arrive on their own and your quantities push back automatically — about ten minutes, start to finish.

New to how ODV sync works? Start with the marketplace sync overview — what syncs, what stays with your listing tools, and how matching works. Otherwise, let’s connect.

Connecting your eBay account

Step 1: add your eBay seller ID

From the eBay section in Ordovee, click Add Connection and enter your eBay seller user ID — the username buyers see on your listings. ODV creates a connection record tied to your account.

Step 2: authorize ODV to access your eBay data

eBay uses two separate channels for different types of data, so you’ll see two authorization buttons:

• REST (Orders) — This connects ODV to eBay’s order fulfillment system. It’s how new purchases arrive in ODV.
• Trading (Listings) — This connects ODV to your active listings. It’s how ODV reads your catalog and pushes quantity updates.

For each one, you’ll click the connect button, log into eBay, and grant ODV permission. You’ll be redirected back to ODV automatically — no codes to copy, no tokens to paste. The page updates to show your connection status as each lane completes.

Step 3: run your first listings sync

Once both channels are connected, head to the eBay Dashboard and click Sync Listings. ODV pulls in your active eBay listings — titles, SKUs, quantities, prices, and item IDs. This creates a mirror of your eBay catalog inside ODV.

This mirror is read-only on ODV’s side. It reflects what’s on eBay right now so ODV knows what you’re selling and can match listings to your internal inventory.

Step 4: run your first orders sync

Still on the dashboard, select a lookback window — 30, 60, or 90 days — and click Sync Orders. ODV pulls in your recent eBay orders: buyer info, order totals, line items, and status.

This first sync is a one-time catch-up. After that, ODV tracks its place with a bookmark and only pulls in what’s new since the last sync. You don’t need to pick a window again.

Step 5: you’re connected

That’s it for eBay. Your connection page now shows:

• Connection status for both channels (connected, with expiration dates)
• A Sync Listings button you can run anytime
• An Auto-Push toggle — when enabled, ODV automatically pushes quantity updates to eBay whenever your internal stock changes
• The four-step inventory push workflow for your first manual push

Making sure your eBay listings have SKUs

Ordovee matches listings to your inventory by SKU, and on eBay, SKUs are optional. If some of your listings don’t have one assigned, ODV can fix that for you.

The Ensure Listing SKU job assigns a unique identifier to each listing that’s missing one, then writes it back to eBay. That SKU is the one field ODV adds — the identifier it needs to match a listing to your inventory; your titles, prices, photos, and categories stay untouched. Once a listing has its SKU, it’s ready for quantity sync. SKUs must match exactly — after trimming spaces and converting to uppercase — and ODV will flag any listing whose SKU doesn’t match an item, so you know exactly what needs attention.

What happens next

With eBay connected, the daily grind changes:

• Orders arrive on their own in Ordovee’s queue, ready for picking — no more watching the eBay dashboard for new sales. (The order lifecycle follows one from arrival to shipment.)
• Quantities push on their own. Add stock, fulfill an order, or adjust a count, and ODV updates your eBay listing. The window where you could oversell shrinks from hours to minutes.

Also on Shopify? The Shopify sync setup follows the same shape, and ODV runs both against one inventory.
