I have attached the billing system SDK. You will be building an anti-fraud plug-in for the billing system (see SDK)
1. you will create a plug-in which will integrate with Maxmind: [url removed, login to view]
2. and the telephone verification service: [url removed, login to view]
3. these will only be checked for new orders
4. we should be able to customize the acceptable fraud scores according to maxmind that it will automatically approve/disprove.
