The UK service provides comparisons of prices for products in a wide range of categories available from competing online sellers. Price quotes include voucher codes that apply available discounts to quoted prices. A Price Watcher function monitors price changes for a product and sends email if a preset price is reached. Product selections include comparisons of airfares across airlines service selected routes. Separate services are available to shoppers and sellers in Germany, Austria, France, and Italy.
Methods allow e-commerce sellers to create and update product and price listings on the service by submitting XML data using the same format as the provider's file-upload service. Updates via the API appear immediately in the service data, while updates via file upload appear after a lag due to batch processes for file handling.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
