my asp site requires users to register in order to view member only information. its currently a free service but im looking at adding some premium membership only information. this will require using paypal or similar for payment transaction. in order for this information to be readily accessable straight after registering as it currently is with free membership i need some kind of varible sent back from paypal to add to my members access database record to indicate successful transaction and therefore can view premium only information. can paypal or similar services provide code to do this? can this be acheived?
