help with asp payment system

[Paul M]

Hi everyone

I am trying to impliment an online game for a charity website I can do the
following

Design the game
Register game players with an access database
and check whether they have purchased credits to play the game

The problem is this.
The person registers and buys credits to play the game. How do I input into
the database the credits they have purchased?
I can do this before they pay by paypal as part of an update statement but
if they decide to not pay when they reach the paypal site, the credits have
already been assigned to ther account How do I assign credits after they
have payed by paypal?


Thanks
Paul M

You would have to use the PayPal API, otherwise do not activate the account until you receive a
notice of payment from PayPal for that user.

The activation would be a manual function, so you would need to create a asp update page to do this.

If you have a bit of programming skill, you can also look at PayPal's IPN
system. this gives you the ability to receive data from PayPal when a
payment is made with the status of the payment. Always be sure to keep a
copy of all the raw data that paypal posts to your IPN page. This is a good
"just in case" because it's easy to miss a payment when unusual data comes
in.

Hope this helps,
