.NET SDK

If you're not sure which API or language you need, see What should I use for my app?

Benefits

• Simplifies the development process by abstracting the eBay API and by supplying 'out-of-the-box' functionality for features and processes that you would otherwise have to build
• Cuts time to market by providing common API modules in an easy-to-use format
• Provides a robust, efficient, and standard integration layer
• Supports the latest features through regularly scheduled updates by eBay
• Can be used in conjunction with an existing eBay API application to enhance functionality, e.g., adding payment processing or inventory management support
