Pay Pal API currency type

I am new at paypal payment system...

I have seen this been done, but i donn't find PayPals Documentation user friendly...

I need to make a payment gateway system, to allow users to use a shopping cart... then they could pay the total through paypal...

so is there a way to use paypal api tell how much the user should be charged e.g: $100 or £100 or however the product(s) might cost? then confirm it... or if there is a tutorial (for newbies/dummie lol ) would be a great help. Also which paypal option/system am I looking to use on this occasion.

hope i have explained myself clearly... thank you .

I can use PHP, and MySQL, JavaScript/JQuery, if necessary and I am confortable with un开发者_开发技巧derstanding them.

(BTW PayPal is the worse documentation i have ever come across lol)

yes paypal can use a authorization & capture solution. You can use GetExpressChecout with setExpressCheckout.

A good solution is to use a DoReferenceTransaction with theses method, in order to use recurring payment.

I have some sample but in c#.
