eBay Integration

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.

Why Connect eBay?

Section titled “Why Connect eBay?”

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.

Before You Start

Section titled “Before You Start”

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.

What Gets Synced?

Troubleshooting

Section titled “Troubleshooting”

Orders Not Syncing

Section titled “Orders Not Syncing”

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

Inventory Not Updating

Section titled “Inventory Not Updating”

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

Connection Expired

Section titled “Connection Expired”

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

Duplicate Listings

Section titled “Duplicate Listings”

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
