Netcetera Demo Merchant (NDM) Simulator Documentation
The Netcetera Demo Merchant (NDM) Simulator serves as a helping component to the 3DS Server in order to complete various flows for testing purposes. The functionality is broken down into three groups:
3DS 2.x flows simulation
Depending on the need, а 3DS 2.x Directory Server, a 3DS 2.x ACS or a 3DS Requestor behaviour is simulated. To support 3DS 2.x flows the NDM Simulator:
- simulates different scenarios of a Directory Server returning a preparation response (valid PRes containing ADD/DELETE card range data, valid PRes without card range data, PRes with invalid serial number, PRes that takes more time than allowed until it is returned, etc.)
- simulates the 3DS 2.x ACS sending a 3DS Method response to the 3DS Method Notification URL
- simulates different scenarios of a 3DS 2.x Directory Server response to an Authentication Request
- simulates a Directory Server sending a RReq to the 3DS Server
- simulates an ACS sending the final CRes to the 3DS Server
3DS 1.0 flows simulation
To support 3DS 1.0 flows the NDM Simulator:
- simulates different scenarios of a 3DS 1.0 Directory Server response to a Verify Enrollment Request (VEReq)
- simulates a 3DS 1.0 ACS sending Payer Authentication Response (PARes) to a 3DS Server
Union Pay flows simulation
To support Union Pay authentication flows the NDM Simulator simulates various responses of a UPOP Server on the following requests sent by the Union Pay Authentication module of the 3DS Server:
- an Authentication Request
- an Authentication Status Inquiry Request
