function customize_s3_url_prefix($prefix) {
    return 'wc-myprefix://'; // Change to your preferred prefix
}
add_filter('wcs3_url_prefix', 'customize_s3_url_prefix');

Reviews

Simple S3 integration for WooCommerce

February 2, 2026
I really love this plugin. It’s exactly what I was looking for to sell digital download products with WooCommerce.It finally makes it easy to integrate S3 files into download products without any coding. I’ve used similar features in Easy Digital Downloads, and I was really happy to see the same solution available for WooCommerce.
