CritFlip and the eBay API

A short summary for eBay reviewers — what the app does, which APIs it consumes, and how we stay on the right side of eBay's developer-program requirements.

What CritFlip does

Web-based arbitrage tooling for eBay resellers. We surface listings, score deals, and route opt-in checkouts through eBay's official OAuth flow.

eBay APIs we consume

Browse · Finding · Trading. We cache aggressively per listing so we use far fewer API calls per visible listing than naive polling would.

Marketplace Account Deletion endpoint

Multi-tenant, live at critflip.app/ebay/account-deletion/<tenant> — verified per eBay's SHA-256 challenge protocol.

EPN affiliate disclosure

Persistent footer microcopy + per-page hero disclosure + dedicated affiliate disclosure page.

Privacy & data retention

See the Privacy Policy for what we store, how long, and how to request deletion.
