Verification API (Required)

The Verification API is used for you to obtain real-time risk verification results.

To effectively prevent fraud and minimize financial losses, it is recommended that you send a request for risk verification before initiating the funds authorization process through the payment gateway. Alternatively, you can also send a risk verification request immediately after receiving the authorization response from the payment gateway but before capturing the funds. This ensures that a thorough risk assessment is conducted before any financial transactions take place.
