Step 4: Sage Pay checks for 3D-Secure enrolment<br />
The Sage Pay servers send the card details provided by your customer to the Sage Pay 3D-Secure<br />
Merchant Plug-In (MPI). This formats a verification request called a VEReq, which is sent to the 3D-<br />
Secure directory servers to query whether you, the merchant, and the card issuer are enrolled in the<br />
3D-Secure scheme.<br />
The 3D-Secure directory servers send a verification response called a VERes back to our MPI where<br />
it is decoded and the Sage Pay system is informed of the inclusion or exclusion of the card.<br />
If the issuer is not part of the scheme, or if an MPI error occurs, our server will check your 3D-Secure<br />
rulebase to determine if authorisation should occur. By default, transactions that cannot be<br />
authenticated will be forwarded to your acquiring back for authorisation.<br />
If you do have a rulebase set up, our system check the rules you have in place to determine whether<br />
you wish the customer to proceed with authorisation, or you require them to select a different payment<br />
method. In such circumstances the shopper will be returned to the card selection page for another<br />
attempt. After the 3 rd unsuccessful attempt, the customer will be redirected to your FailureURL with<br />
a Status of REJECTED and a StatusDetail indicating the reason for the failure. The<br />
3DSecureStatus field will contain the results of the authentication. REJECTED transactions will<br />
never be sent for settlement and the customer never charged, your failure page should explain why<br />
the transaction was aborted.<br />
If your rulebase does allow authorisation to occur for cards not enrolled, the next step is for the system<br />
to obtain this from your acquirer (see Step 7).<br />
In most cases 3D-Secure verification will be possible and the process continues in the next step.<br />
