The Structure of a SOAP Request
A SOAP request is an XML data structure generated by a SOAP toolkit that is sent to a web service. The root element of this structure is named after the operation and contains the values for the operation's parameters.
The root element of every request must contain:
-
A value for AWSAccessKeyId to authenticate the request
For more information, see AWS Access Key ID
-
An endpoint, which is the destination for the request
For more information, see Request Terms That Remain the Same
-
A request element, which contains the values for the operation's parameters
The API Reference describes all of the Product Advertising API operations and their parameters. The Product Advertising API WSDL shows how the operation parameters appear in the XML request generated by your toolkit.
