<p>
A key-value map specifying request parameters that are passed from the method request to the back end. The key is
an integration request parameter name and the associated value is a method request parameter value or static
value that must be enclosed within single quotes and pre-encoded as required by the back end. The method request
parameter value must match the pattern of <code>method.request.{location}.{name}</code>, where
<code>location</code> is <code>querystring</code>, <code>path</code>, or <code>header</code> and
<code>name</code> must be a valid and unique method request parameter name.
