I'm a bit of a newb and have never integrated paypal into a website before so I apologise for my lack of knowledge.
I'm trying to build a website which allows users to sign up and, assuming they get themselves paypal premier accounts (so they can receive payments by credit card) they will be able to receive payments from other users of my site.
So someone will sign up using their Paypal email address, and other users will then be able to send them money through my site. If they use one of my special services then I also want to be able to take a 1% fee of the money sent.
I'm using cakephp and I've searched and found a few cakephp related paypal components but to me it seems that these are aimed at people who want to just use their own paypal account to receive money. Like having a paypal checkout button. Whereas I want to be able to direct money into many different paypal accounts. Is this possible? And if so can any kind soul direct me to where I should be reading (pref something not too difficult - I'm a learner!).
Also as a side note, are there any special security issues I need to take care of when dealing with paypal, especially considering the particular nature of what I want to achieve? How easy would it be for a bad person to alter someones paypal email to direct funds to themselves?
many thanks in advance
