Kunena, Joomla, Envato API Integration

I need an integration with Envato API and Kunena 3.0 Forum - Component for Joomla 3. This would be Kunena plugin This is what need to be done: 1. User would register on my site 2. On Registered User Forum Profile (When goes to Edit mode) there would be tab saying Envato and in that tab a text area where he/she can paste his purchase code, e.g. verify-purchase:550e8400-e29b-41d4-a716-446655440000 one per line. 3. This would automatically grant him privilege to post and read specific forum category that i set based on the product that she or he bought on envato network (ThemeForest) or multiple categories. 4. I would set this in Category Manager in Kunena need to add one tab named Envato (add in that tab need to be listed all my products with checkboxes) Envato API : [login to view URL] Kunena 3.0.0 Beta - [login to view URL] , [login to view URL] Joomla 3 - [login to view URL]
