I was wondering if it’s possible (by Envato API) to validate a purchase using customers Username and API Key combination, instead of standard purchase code validation.
In ideal world, a customer would add their Username / API Key within theme settings on WP admin panel, and validation would check if the item is available in customers ‘downloads’ folder within the Envato marketplaces.
I would suggest to use what you have at the moment, improve it a bit, and add on different elements, in order to make a broadcast package. I believe it would sell more there, and it has some potential on that field.
Also, I would try to get rid of the ‘shining’ effects, it would look much better flat.
