We need help in adding paypal as a payment option to our existing e-commerce site. we also need a way to verify that payment went through. since the site is in Adobe Flex, a new window will open up to logon to paypal, but then when it returns, our site must know that the transaction will went through. we need someone with the expertise to provide the code and guide us on how to get this done. in case any server processing is needed, a ColdFusion CFC will be required.
