Some parameters, however, can be repeated in a request. In that case, the parameter names are
differentiated by adding a period (.) after the parameter name and then a sequence number, as shown
in the following example.
Item.1=1234&
Item.2=2345
Other parameters can be repeated but, in addition, have associated parameters. These parameters
extend the preceding example by adding another period and the associated parameter name, as shown
in the following example.
Item.1.ASIN=3456789123&
Item.1.Quantity=2
In this example, the item being added to a shopping cart has an identifier, the ASIN, and a quantity value.
The equivalent expression in an XML document is, as shown in the following example.
<Item>
<ASIN>3456789123</ASIN>
<Quantity>2</Quantity>
</Item>
The sequence number associates the identifier and its quantity value. The following example shows two
compound parameters.
Item.1.ASIN=3456789123&
Item.1.Quantity=2&
Item.2.ASIN=123456&
Item.2.Quantity=1
The sequence numbers associate the ASIN and quantity values.This means that the compound parameters
can be written in a different order without causing a problem.
Item.1.ASIN=3456789123&
Item.2.ASIN=123456&
Item.1.Quantity=2&
Item.2.Quantity=1

SOAP Requests

Product Advertising API supports the SOAP message protocol for calling Product Advertising API operations
over an HTTP connection. The easiest way to use the SOAP interface with your application is to use a
SOAP toolkit appropriate for your platform. SOAP toolkits are available for most popular programming
languages and platforms.
The service's Web Services Definition Language (WSDL) file describes the operations and the format
and data types of their requests and responses. Your SOAP toolkit interprets the WSDL file to provide
your application access to the operations. For most toolkits, your application calls a service operation
using routines and classes provided or generated by the toolkit.
