EA Protection & Licenses

I need to protect my EA with License integrate with ClickBetter.com

Need to Automatic adding clients and automatic removing refunded clients.

Script Example here:https://mqllock.com/clickbetter-integration/ 

Require IPN:

IPN is Instant Payment Notification, IPN makes possible that ClickBetter clients´s scripts get notified automatically upon new order has been received or someone has requested refund. With IPN its possible to automate sales and refunds and re-act almost realtime. You will not need any manual interaction anymore if you have setuped IPN Backend. Typically IPN is a script hosted on your server, you have to tell ClickBetter about your URL and ClickBetter will send data to this url internally. Your clients (person who has purchased the product) does not see anything, everything happens automatically in background
