Affiliate website

I want a website, where user can add their sports affiliate accounts, and then it will save and update the stats every day. Example: I use Bet365 and Betfair affiliate program. Then I will go to my site and add Bet365 and Betfair with the affiliate program username/password, some way, I don't know how. Then the stats will be updated every hour, so I don't have to visit bet365's and betfair's own site to check the stats, but all the stats will be at one place (my site). I don't know if this is possible, and I don't know how to get the data, because there is no API available, but maybe if we could integrate the bet365's affiliate programs website, and then user can login, and it will save the data it gets from there. The site will be made on Wordpress. I have the theme and website ready. Let me hear how you will handle this project.
