eBay Marketplace

Catch margin and promo drift on eBay before it ships.

Decionis normalizes eBay Sell-API orders, fees, and promotions into the same deterministic margin and promo-hygiene gates that run your Shopify checkout — allow, hold, or escalate — and records a signed Decision Dossier into the cross-surface audit ledger. Connect with eBay OAuth; runs shadow-mode first while we validate against live seller accounts.

Sell-API connector built and mock-verified; live verification against a real eBay seller account is pending. Runs in shadow mode (observe + signed dossier), never enforcing until validated.
