eBay API

API

Integrate eBay's buying and selling capabilities into your applications

Overview

The eBay API provides RESTful endpoints to access eBay's marketplace features, including item search, listing creation/management, order processing, user account retrieval, and payment integration. Responses are primarily JSON (with XML support for legacy endpoints). Key use cases include building price comparison tools, automated inventory sync systems for sellers, custom storefronts, and order management dashboards. It uses OAuth 2.0 authentication and offers a sandbox environment for testing without live data, supporting both buyer and seller workflows.

Example Integration (JavaScript)

script.js JS


fetch('https://developer.ebay.com/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
