Connect eBay

  1. 1Open eBay settings from the sidebar (or Settings, then the eBay tab).
  2. 2On the Overview tab, choose Connect eBay.
  3. 3Sign in to eBay and approve CardZen's access.
  4. 4Back in CardZen, confirm the Overview tab shows Connected — all permissions granted.
  5. 5Set your payment, shipping, and return policies on the Policies tab before you list.

What's on the eBay settings tabs

eBay settings is organized into tabs:

  • Overview — connection status, connected account, listing limits, and Disconnect.
  • Policies — your default payment, shipping, and return business policies.
  • Defaults — pricing inputs, format, Best Offer, duration, and other new-listing defaults.
  • Pricing — pricing strategy settings.
  • Templates — title and description templates.
  • Photos — auto-crop and image settings.
  • Notifications — what eBay events CardZen alerts you about.

What eBay can sync

  • Active listing data, traffic, and offers.
  • Purchase and sales history within eBay's current 60-day import window.
  • Itemized sales fees when the connected account grants finance access.
  • Your listing policy choices.
  • Listing publish and revise status.

Create a card from a listing

An imported eBay listing with no card behind it gets a Create card action. CardZen reads the listing's details, including a parallel named in the title, and first photo into one inventory card and links the two. Nothing changes on eBay.

Before it creates anything, CardZen checks whether you already have that card and shows you which one it means. Choosing it links the listing to that card instead of adding a second record for the same physical card, which is what would otherwise split that card's money across two rows. Own a second copy? Choose Create new card and the first one stays untouched.

  • Linking to a card you already photographed uses no scan.
  • Creating a new card from the listing uses 1 CardSense scan.
  • A card that is already sold, or already carries a live listing, is never offered.
  • You can convert several listings at once from the listings table.

Search sold listings on eBay

eBay now requires a sign-in to view sold and completed listings. Wherever CardZen shows comps — the card editor, the listing comp panel, and Card Show on the iPhone app — a Search sold on eBay button opens eBay's sold results for that card, already filled in. It moves front and center when CardZen has no sold comps of its own to show.

The button uses your own eBay sign-in. Sign in once and later opens land straight on the results. CardZen only opens the page — it doesn't read anything back from it.

How often eBay data refreshes

Sync from eBay reads special characters in listing text, such as ampersands and quotation marks, as normal text. Syncing listing details does not overwrite a saved card title or change the live eBay listing.

Opening Listings shows CardZen's saved listings immediately while any needed refresh runs in the background. Visit again to see refreshed data, or press Sync from eBay to refresh it immediately.

Once your account is connected, CardZen keeps it current on its own — there's nothing to press. Sales arrive as eBay reports them, and a twice-daily sweep catches anything the live feed missed. Best Offer checks cover every active listing on your account together, so pending offers and cleared offer counts stay current throughout the day. Listing views and impressions are recorded once a night, which is why a new listing's traffic chart fills in day by day rather than all at once.

Automatic listing-status checks rotate through connected sellers over a 12-hour window. They pause when eBay's shared request allowance is nearly used, keeping room for you to publish cards. These checks do not refresh individual listing details; choose Sync from eBay on the Listings page when you want those updated.

Reconnect when asked

eBay tokens expire, and older connections may not include every permission CardZen now uses. If CardZen asks you to reconnect for fee sync or account access, just run the Connect eBay flow again — your existing CardZen records stay in place. The Overview tab is also where you'll see a warning if the connection ever needs attention.
