Our Buy APIs enable developers to build buying experiences where consumers can purchase products from eBay anytime, anywhere—wherever consumers are online.

  • Use cases: eBay’s Buy APIs are designed to enable social sites, merchants, or marketplaces who want to virtually increase the inventory they offer to their customers.
  • Benefits for sellers: Contextual commerce helps eBay sellers to list their inventory on eBay and enable shoppers to discover that eBay inventory anywhere on the Web, including social sites and other contexts.
  • Opportunity for 3rd-party developers: For eligible developers, eBay’s Buy APIs expand the potential customer segments that developers can offer their services to and create opportunities for new types of integrations that you may have never thought possible.

As an eBay Partner Network affiliate or Buy API Partner, you can drive traffic to eBay via the traditional affiliate model, or let your customers browse eBay items and purchase these items without leaving your site—also known as contextual commerce.

As a developer, you can create experiences that seamlessly integrate eBay shopping into social sites, DIY blogs, and specialized digital magazines and forums; or you can create websites and applications that bring eBay inventory into new geographical markets or into other enterprise shopping experiences.
