This eBay PHP library interacts with finding API, shopping API, and trading API. Tutorials to work with the three APIs include find best price and keywords for the finding API; retrieve information about a seller and affiliate parameters for the shopping API; and listing & bidding auctions for the trading API. Created by developer Rick Earley.
The Vibetrace API integrates Vibetrace's recommendation engine, accessing virtually any e-commerce platform. The name of the game, of course, is to move people from your target market to become visitors, then shoppers, regular customers and finally, part of your engaged community. Vibetrace's secret sauce for increasing conversion rates is a csutom built recommendation engine. It joins nearly 200 e-commerce APIs in our directory.
