Does anyone know how to set up a post back persona.ly

So I own my own social exchange website its going farely ok as I have just over 200 members so far. Not sure if any of you herd of sites like Super rewards and persona.ly which pay members for doing daily tasks to surveys and also downloading apps. Well I have added super rewards easy on my website now am struggling at the minute making a persona.ly as I joined it and asks me to create a postback setting on my server and not really sure how to do this .

Any help would be brilliant am fairly new to scripting and coding but learned few tricks. There is so much I still need to do just at the minute trying to figure out this persona.ly settings.
