Using Clickbank Instant Notification Service to Create Individual Username/Passwords for Customers

Hi everyone,

So I currently have a product I want to sell via clickbank. I was originally going to sell the product as a DVD, but in order to provide instant access to the customer (and to hopefully get my product out sooner) I decided to put the videos in a member section of my site, which is built using optimizepress.

However, I wasn't sure how to generate a username and password for each person when they bought my product using clickbank. After looking into it, it seems that the Clickbank Instant Notification Service is probably the way to go? Is that right?

If so, can I get some advice on the best way to do this? It doesn't look like the script would be that hard to write? But I think there are already existing products that do this out there as well?

Does anyone have any experience with generating usernames/passwords for a product sold via Clickbank and would you mine sharing your experiences/advice in this?

Any related info would be appreciated.

Thanks!
