question

I am looking for the documentation for Amazon Instant Access, but can't seem to find it anywhere. I saw it originally referenced here: https://developer.amazon.com/appsandservices/community/post/Tx3VAMG90LQR7DF/Amazon-Instant-Access-Sell-Digital-Items-for-Your-PC-Mac-or-Web-Based-Applicatio To provide some context, I run a marketplace for business documents (e.g. PowerPoint presentations, Excel workbooks) and would like to list these digital documents on Amazon. Any help and guidance is greatly appreciated. Thanks.
