Check the status of other shopping sites (such as excellent, when) orders (i.e. tracking orders)
Now I am doing a shopping return site, the site itself does not sell things, but let users through my site to when the site of excellence and so on to buy things, and then when the outstanding to my cashback back to the user. When the excellence will give me some information about the order, but it seems to be the Web interface feedback, do not know whether there is no interface or the like. How to keep track of the orders of users when waiting for the site. Hope to have done this kind of project friends to help answer the next

It's also similar to the CPS business of the ad-affiliate system (pay-as-you-go), I just don't know how to track "Effects", that is, tracking the registration behavior or buying behavior of other websites that the user has gone to from me.
