Whatnot

Whatnot integration

Whatnot is the dominant live-selling marketplace for trading cards in North America. Storefront Pro supports Whatnot sellers on the inventory and fulfilment side — your Storefront Pro inventory is the single source of truth, sold items decrement centrally, and post-stream fulfilment flows through your existing order pipeline. Direct API integration is on our roadmap.

Capabilities

What the integration does

Concrete features, not marketing bullets.

  • Export Storefront Pro inventory to Whatnot listing format
  • Decrement stock after a Whatnot stream from a single source
  • Fulfil Whatnot orders through your existing Storefront Pro pipeline
  • Run live auctions natively on your own Storefront Pro site (alternative to Whatnot-only)
  • Reconcile Whatnot sales into your unified sales reporting
Limitations

What it doesn't do

We'd rather tell you the limits up front than have you discover them after signup.

  • Direct Whatnot API sync is on roadmap — current support is workflow-based
  • Real-time stock decrement during a live Whatnot stream requires manual reconciliation
  • Whatnot-specific promo tooling is not replicated inside Storefront Pro
FAQ

Frequently asked questions

Can I sell on Whatnot and still use Storefront Pro as my source of truth?
Yes. Storefront Pro remains your inventory master. Whatnot listings are created from your Storefront Pro catalogue, and post-stream fulfilment flows back into your Storefront Pro order pipeline.
Why not a direct API sync?
Whatnot's seller API surface is more limited than TCGplayer or Cardmarket for catalogue-level sync. Full API-level parity is on our roadmap as Whatnot expands its seller tooling.
Do you offer live auctions on my own site?
Yes. Storefront Pro includes native live auctions and live streaming — a direct alternative to Whatnot where you keep 100% of the margin and the customer relationship.
Is this integration included in Storefront Pro?
Yes. All inventory, fulfilment, and live-auction features are included at £1,000 setup + 2% on sales.
