Micropayment integration in Jommla website

We need to integrate the micro-payment system ALLOPASS on an adult (no explicit material at the moment) website to allow user downloading videos. An article is created for each new video. Of this article intro text, some pictures, a trailler video streaming and a link (button allopass) to download the video. This link should trigger the script allopass purchase, authorize the payment and afterdownloading the video. The mission is to enable us to integrate allopass button on new articles and be able to simply select the video to download (different for each page but same price, same allopas item) Here is the specs : > Creating a plugin "Allopass" - Generate a code to be integrated into the articles to generating the display of the button "buy" as follows: { allopass} [login to view URL] {/ allopass} > Back office: - Plugin configuration (code integration provided by Allopass, location of the directory where videos are stored); - Plugin button in the editor to choose the video and automaticaly insert the code > Frontend: - Automatic display of the button "buy" in the articles where the code is embedded; - Unlock (and launch?) the download of the video selected after the payment success; - Send an email notification (to admin) for each payment with the time, the IP and if possible the name of - Recording of transactions in DB; - table view in frontend (admin logged) with payment history (date / time, IP, video); IMPORTANT : please be sure you can handle the AlloPass API (attached) before place a Bid and be sure all the specs can be done.
