eBay Etsy Integration
Nventory syncs inventory counts between eBay and Etsy in real time and imports orders from both into a unified dashboard. When a unit sells on one marketplace, Nventory updates the other within seconds to keep stock accurate.
Sync Matrix
5 data entities in the sync matrix — 2 bidirectional, 3 one-way. Tap any row for details.
Good to Know
Platform restrictions outside any integration tool's control
Etsy charges $0.20 per listing with four-month auto-renewal. Nventory syncs quantities but does not manage listing fees, renewals, or Etsy Ads billing.
Individual bid amounts and bidder identities are not accessible via API. Only winning bids sync as completed orders.
Both platforms' seller performance badges are calculated internally. Nventory helps maintain compliance by preventing oversells but cannot directly access badge qualification data.
Things to Consider
Platform-specific details and how they affect this integration.
Vintage and handmade items frequently have a quantity of exactly one. Both eBay and Etsy attract buyers for these unique items, creating a constant risk of double-selling irreplaceable inventory. The item cannot be re-sourced or reproduced if sold twice.
Nventory uses priority zero-out logic for items flagged as one-of-a-kind. The moment a sale is detected on either platform, the other listing quantity is set to zero within seconds. Near-miss alerts notify you of any close-call events.
Who Uses eBay Etsy Integration
Common scenarios for connecting eBay and Etsy.
How It Works
Nventory sits between your platforms and keeps everything in sync.
Authorize Both Shops
Connect your eBay Seller Hub and Etsy shop to Nventory using secure OAuth tokens. Existing listings and active orders import automatically.
Link Matching Products
Nventory matches eBay items to Etsy listings by SKU or manual mapping. Unique and one-of-a-kind items are flagged for careful quantity tracking.
Set Niche-Specific Rules
Configure rules for vintage items (quantity of one), handmade items with production lead times, and craft supplies with higher stock levels.
Activate Continuous Sync
Inventory quantities, orders, and tracking information sync between eBay and Etsy through Nventory in real time. Alerts flag any mapping or quantity conflicts.
Frequently Asked Questions
When a unique item with quantity one sells on either eBay or Etsy, Nventory immediately sets the other listing's quantity to zero. This happens within seconds, drastically reducing the window for a double-sale.
Yes. Nventory reserves the auctioned quantity on eBay so your Etsy available stock only reflects uncommitted inventory. If the auction ends without a sale, the stock is released back to Etsy.
Nventory focuses on physical inventory sync. Digital downloads on Etsy can be excluded from sync rules since they do not consume physical stock.
Products only listed on one marketplace are tracked independently in Nventory. They appear in your inventory dashboard but do not trigger cross-marketplace sync unless you map them to a counterpart listing.
Stock changes propagate within seconds. This is especially critical for vintage and one-of-a-kind items where a single unit is listed on both platforms. Nventory polls both eBay's and Etsy's APIs at high frequency to detect sales as fast as possible and push zero-out updates to the other marketplace.
Nventory applies priority zero-out logic for items with a quantity of one, instantly setting the other listing to zero the moment a sale is detected. For items with slightly higher quantities, configurable safety stock buffers ensure the last unit is never exposed on both platforms simultaneously, protecting against double-sales of irreplaceable vintage or handmade inventory.
eBay titles are limited to 80 characters while Etsy allows up to 140, so titles that fit on Etsy may be truncated or rejected when pushed to eBay. Category taxonomy differences between the two platforms can also cause mapping failures — an Etsy category like 'Craft Supplies & Tools' has no direct eBay equivalent and needs manual mapping. Finally, check image requirements: eBay enforces minimum resolution and white-background preferences that Etsy's more lifestyle-oriented photos may not meet.
