enable 2CheckOut payments in the control panel:

- Click the Edit button to activate it.
- Enter the required parameters in the 2CheckOut form:

(HS 2.5 RC2 and up) 2CheckOut Servers IP where payment notification
requests come from. Payment requests from other IPs will be rejected which helps to avoid fraud.
Note: You can enter IP mask instead of IP, for instance 127.0.0.* or 127.0.*.*
- 2CheckOut Merchant ID: your ID provided to you by 2CheckOut.
- Check the box if you want to Use Authorize.Net WebLink parameter names.

- If V2 System Support (v.2.4.2 Patch 1 and up) is checked, the system will apply
a new http routine used with the V2 2Checkout system.
Note: 2CheckOut is transferring all customers to V2 System. Therefore we recommend enabling this option.
