eBay is continuously improving the features it offers buyers and sellers. Now, the biggest improvements are ones you can build for yourself.

Mining eBay Web Services teaches you to create custom applications that automate buying and selling tasks and make searches more precise. Do you have dozens of items to sell? You can prepare complete descriptions and terms and submit them all with one click. Are you searching for an item with special purchasing or shipping conditions? You can't do this manually, but your custom application can. Would you benefit from charting your buying and selling trends? This book shows you how to mine and organize information that simply isn't available otherwise.

All by itself, the improvement in speed will dwarf anything you've experienced—especially if you connect to eBay via dial-up. But speed is just one piece of an entirely new way of navigating the eBay marketplace. Here's a little of what you'll find covered inside:

• Creating new listings in bulk and automatically submitting them
• Getting all the facts you need about an item in one step
• Performing searches based on shipping or payment terms
• Completing tasks more quickly by working with locally stored eBay data
• Working with eBay's new authentication and authorization technology
• Ensuring the accuracy of your listings
• Quickly accessing buyer and seller information
• Using the new Java and SOAP interfaces
• Using calls to perform tasks not supported by the manual interface
• Charting trends in your buying and selling habits
• Tracking eBay listings with mobile devices
• Developing secure applications
• Automatically submitting feedback in batches

You'll learn to do all of this and more using the language of your choice: JavaScript, VBA, Visual Basic 6, Visual C++ 6, Visual Basic .NET, C#, PHP, or Java. You also get all the details on participating in various eBay developer programs, where everything you need as an individual is completely free.
