I'm not sure where to exactly post this. There is a website called mint.com which let's you enter your username and password for a bank, stock broker, etc and the aggregates all your information from all different accounts onto one screen (balances, transactions, etc).
How does mint.com do this? I highly doubt all the 6,500 financial institutions they support have API's to access. Put another way, if I wanted to aggregate all my private emails on DaniWeb and I had the my username and passsword, how can I do say programatically?
I assume it's something do with AJAX .
