Stash plugs into the marketplaces you already sell on. eBay is a real-time API integration; Whatnot and HipComic use CSV upload / download.
eBay (API)
The deepest integration. Once you connect, you can publish listings directly from inventory, see your active listings, and record sales automatically when buyers pay.
- Settings → Marketplaces → eBay.
- Click Connect eBay. You’ll be redirected to eBay, sign in, and approve our app’s access scopes.
- You’re back on Settings → Marketplaces. eBay shows as connected with your seller username.
- From any inventory item, click Publish → eBay, pick condition / starting price / format, submit.
Listings sync both ways: items you mark Sold in Stash get ended on eBay; items that sell on eBay get marked Sold in Stash via webhook (Seller tier and above).
Whatnot (CSV)
Whatnot doesn’t have an open API yet, so we use their CSV exports. After a stream:
- Download your sales export from the Whatnot seller dashboard.
- Settings → Marketplaces → Whatnot → Import sales.
- Map columns (one-time; we remember per workspace), import. Matched items get status=sold + sold_price + date_sold set; rows with no matching item are listed at the bottom for you to manually link or skip.
HipComic (CSV)
Same workflow as Whatnot — download your sales/listings CSV, map columns once, import. Listings get pulled into the Listed state with a back-reference URL.
Other marketplaces
Stash recognizes 8 other marketplace platforms for tracking purposes (mark items as Listed-on-X). For most you’ll upload listings manually on their site and just record the listing in Stash to keep your inventory accurate.
Publishing in bulk
From Inventory:
- Select multiple items via the checkbox column.
- Click Publish in the floating action bar.
- Pick the target marketplace. For eBay you can set per-item or shared pricing rules. For CSV marketplaces, you’ll get a CSV ready to upload.
Rate limits
- eBay listing creation: 10/minute per workspace.
- eBay sync operations: 5/minute per workspace.
These are generous for typical workflows; if you hit them consistently, batch up your publishes or use the AI assistant to space them out.
