I am looking for the best API or all the printing website, e.g. smugmug, printroom, exposuremanager, etc... I currently use Exposuremanager and i love them but didnt see much of an API i really need t be able to track back sales from my website lets say someone adds photos to a cart then pushes to EM.. then they cancel out at last min i need to get that info of whether they cancled out or went through with the order... if anyone knows a current website who has an API which will do this pleae let me know 
Thanks!
