I am trying to use the Amazon Product Advertising API and I use the class AwsV4 to sign my request.
I get the message: Uncaught Error: Class 'AwsV4' not found although I have included the libraries.
I have followed the instructions from Installing the AWS SDK for PHP Version 3 - AWS SDK for PHP in section Installing by using the ZIP file.
I downloaded the zip, extracted in and included the file that says in the guide. require '/path/to/aws-autoloader.php'
Anybody knows something? Should I include something else that is not mentioned? I am on windows, PHP 7.
