Rolan:

As I answered to someone else privately:

I use two different methods to handle PayPal purchases:

[1.] One is to use their code and my product ID for simple 
transactions, as seen here:

The item number and buyer specifics is provide back from PayPal so I 
know what was purchased and who purchased it.

[2.] The other is where my code determines the amount; sends a 
request for authorization to PayPal with the users name, cc#, CIV, 
and amount; waits for an authorization back from PayPal; and when 
that happens, it records the purchase and the transaction 
authorization in the database.

[1] is simple -- you use PayPal to collect all the sensitive data.

[2] is involved -- you need a merchant account with PayPal and there 
are liabilities and responsibilities to consider.

Cheers,

tedd
