lib/Amazon/API.pm  view on Meta::CPAN

the Amazon API ecosystem is their use of multiple forms of input to
their methods indicated by the required Content-Type for different
services.  Some of the variations include:

 application/json
 application/x-amz-json-1.0
 application/x-amz-json-1.1
 application/x-www-form-urlencoded

Accordingly, the C<invoke_api()> can be passed the Content-Type or
will try to make "best guess" based on the input parameter you passed.
It guesses using the following decision tree:

=over 5

=item * If the Content-Type parameter is passed as the third argument, that is used.  Full stop.

=item * If the C<parameters> value to C<invoke_api()> is a reference, then the Content-Type is either the value of C<get_content_type> or C<application/x-amzn-json-1.1>.

=item * If the C<parameters> value to C<invoke_api()> is a scalar, then the Content-Type is C<application/x-www-form-urlencoded>.
