To use the eBay API Kit most effectively, you should have a working knowledge of XML and be able to produce an application capable of communicating across the Internet using the HTTP protocol. However, users of third-party applications who wish to interact with the eBay database must also be registered with eBay. There is a basic passing of user information which requires this. There are certain storage and usage restrictions with regard to user data, whether this information is extracted from the eBay database or given to you by an eBay user. For example, a userID and password given to you by an eBay user, if stored in your database, must be encrypted.
Developers can create their own look and feel to a certain extent.
There are certain contractual restrictions on how you can display the data which are discussed in our licensing agreement. This is one of the many benefits of being a licensed API developer. We provide you with complete documentation, technical support and access to a developers web site which contains workarounds and discussion boards. How you develop the application will be left entirely up to you. 1995-2000 eBay Inc. All Rights Reserved.
