Overview

About eBay

eBay's API ecosystem spans the legacy Trading API, the modern Sell APIs (Inventory, Listing, Account, Marketing), and the Buy APIs. We work fluently across all of them, choosing the right API for each use case and managing the OAuth refresh, regional endpoints, and rate limit behavior correctly.

Common questions about
eBay integration

We use the modern Sell APIs by default. We fall back to the Trading API only for endpoints that haven't migrated yet (e.g. some feedback flows).
