Hi There.
Where I could find out a plugin or code that allows me to put a button in an external website that if pushed down makes a transfer points from one user to another, from my website directly? Example: "Peter" is the webmaster of site A. To download a file from it, the guest have to push the button "donate 5 points". Once guest have pushed it , is redirected to my website, and thanks to "points from user to user" plugin, the guest gives the points to Peter. Once done it, guest is redirected into the Peter site to download the file.
Is it possible?

Thanks a lot
