I have an application that allows users to upload an audio file (e.g. MP3) and then extracts the waveform data and draws it onto a canvas using D3.js. The application then exports the drawing to a printable PDF file.
It would take a lot of work to build shopping cart functionality natively into the application so I'm looking for somebody who can help me to integrate the checkout process with WooCommerce.
This will include attaching the custom PDF to their order as a downloadable file.
Is this possible and can anybody offer some potential solutions?
