eBay Integration

Connect your eBay seller account and sync listings, orders, and inventory automatically

Connect your eBay seller account to OmniOrders and manage everything from one place. Your listings, orders, and inventory will sync automatically—no more manual updates or switching between platforms.


Connecting your eBay account to OmniOrders means new orders flow in automatically, inventory levels stay in sync across all your channels, and fulfillment updates push back to eBay the moment they happen — no manual imports, no overselling, and no switching between platforms.

Auto Sync Orders

New eBay orders flow directly into OmniOrders as they come in—no delays or manual imports needed.

Real-Time Inventory

Stock levels update automatically across eBay and all your other channels. This prevents overselling.

Listing Sync

Product listings sync bidirectionally. Add or edit in one place and changes reflect everywhere.

Tracking Updates

Shipping info and tracking numbers automatically update in eBay when orders ship.


Gather these items before connecting—they make setup faster and smoother:

eBay Seller Account

You need an active eBay seller account in good standing. Business or personal accounts both work. Check your account status in eBay Seller Hub.

Active Listings

Have at least one active listing before connecting. This lets you verify the sync works correctly right after setup.

Business Policies (Recommended)

Set up your shipping, payment, and return policies in eBay before connecting. This speeds up listing creation and reduces errors.


  1. Go to Integrations

    In OmniOrders, click Integrations in the main menu, then click Add Integration

  2. Select eBay

    Find eBay in the list and click the Configure button.

  3. Sign In with eBay

    You’ll be redirected to eBay. Sign in with your seller account if prompted

  4. Authorize Access

    Review the permissions and click Agree to authorize OmniOrders

  5. Configure Settings

    Back in OmniOrders, choose what to sync:

    • Listings: Sync your product catalog
    • Orders: Import new orders automatically
    • Inventory: Keep stock levels in sync
    • Fulfillment: Send tracking info back to eBay
  6. Start Sync

    Click Start Sync to begin importing your data. This may take a few minutes depending on your catalog size.


The eBay integration syncs listings (titles, descriptions, SKUs, variants, images, pricing, quantities), orders (line items, buyer addresses, notes, payment and fulfillment status), and inventory updates — bidirectionally, so changes in either eBay or OmniOrders reflect on both sides in real time.

  • Listing titles and descriptions
  • SKUs and item IDs
  • Variants (sizes, colors, etc.)
  • Images and pricing
  • Quantity available
  • Order details and line items
  • Buyer shipping addresses
  • Order notes and messages
  • Payment status (paid/unpaid)
  • Fulfillment status
  • Stock levels by location
  • Quantity updates (both directions)
  • Low stock alerts
  • Tracking numbers
  • Carrier information
  • Shipment status updates

Check if everything is syncing correctly:

  1. Go to IntegrationseBay
  2. View the sync dashboard showing:
    • Last sync time
    • Listings synced
    • Orders synced
    • Any errors or warnings

Need to temporarily stop syncing?

  1. Open your eBay integration settings
  2. Toggle Sync Active to OFF
  3. Syncing stops immediately (you can resume anytime)

Change what syncs:

  1. Click Settings on your eBay integration
  2. Toggle any sync option on/off
  3. Click Save Changes

How often does it sync?

Orders sync instantly when created. Listings and inventory sync every 5 minutes or when you make changes.

Can I connect multiple eBay accounts?

Yes! Connect as many eBay seller accounts as you need. Each account syncs independently.

What about unpaid orders?

Only paid orders sync by default. You can change this in settings if you want to import unpaid orders too.

Is my data secure?

Absolutely. We use OAuth 2.0 secure authentication and encrypt all data in transit and at rest.


Problem: New eBay orders aren’t appearing in OmniOrders

Solutions:

  • Check that Order Sync is enabled in integration settings
  • Verify the order is marked as Paid in eBay—only paid orders sync by default
  • Look for error messages in the sync log
  • Try clicking Force Sync to trigger a manual refresh

Problem: Stock changes in eBay don’t update in OmniOrders (or vice versa)

Solutions:

  • Confirm Inventory Sync is turned on
  • Check if listings are mapped correctly (same SKU in both systems)
  • Verify quantity is set on the listing in eBay
  • Allow up to 5 minutes for updates to sync

Problem: eBay integration shows “Connection Expired” or “Authentication Failed” error

Solutions:

  • Click Reconnect and authorize access again
  • eBay tokens expire periodically—reconnecting refreshes them
  • No data is lost—syncing resumes immediately after reconnecting

Problem: Listings appear twice after connecting eBay

Solutions:

  • Go to Products and use Merge Duplicates tool
  • In the future, ensure products aren’t created in both systems before connecting
  • Use SKU matching to prevent duplicates
