This
is a list of few of the more common Web Service APIs that we are likely to use:
eBay
Google (Calendar, Checkout, Maps, Search)
Microsoft (Live, MSN, XBOX)
Yahoo! (Mail, Maps, Search)
The API and service that we use determines the way in which we handle the API.
We will take a look at the Yahoo! Search API. Before we start, we need to discuss the
Yahoo! Application ID.
Yahoo! uses a unique ID to identify the applications that use its API. If you intend to
use the Yahoo! API, it is important that you register your application before you start
development. This will ensure that you are able to obtain the desired ID.
Most Web Service APIs require us to use an ID of some description.
This allows the owners of the API to analyze the usage of their services.
For the purposes of this example we will use the application ID YahooDemo??”this is
the default ID used when demonstrating the use of the Yahoo Search API.
The first thing that we need to do to create our Yahoo! Search is build the request
query that we will use to obtain the results.
