Paid subscription auto updates karma points

[doa24uk]

Hi guys,

I have 4 paid subscription options available on my site. They're to purchase blocks of karma points.

I want a successful payment to automatically update the user's karma points in the database.

Eg. A user (mrusername) orders a block of 20 karma points. I want the successful transaction status to automatically update the user database to +20 karma points for mrusername.

Is this possible??

Thanks
