Activating and Configuring the Buyer Authentication Service

Configuring Buyer Authentication

Generate Transaction Request Software

1. Submit a Verify Enrollment transaction request (type E) to determine whether the

cardholder is enrolled in either the Verified by Visa or MasterCard SecureCode service. See

the example on page 38.

2. The response is either Enrolled or Not Enrolled. See the example responses on page 38.

3. If the customer is enrolled, you populate the response data into a form page (hosted on your

server) and post it to the URL of the card issuing bank (ACS) indicated in the response.

Make sure the TermUrl field is properly specified, as this is where the ACS will post the

response. See “Example ACS Redirect Code” on page 35.

4. The ACS responds to the post by presenting an Authentication window to the customer.

By Visa/MasterCard requirements, the HTML page for displaying the ACS form must be

presented in-line (within the same browser session as the e-commerce transaction),

preferably as framed-inline.

The ACS form should be displayed in a frame set, as shown in the following example. The

message across the top of the frame is required.

NOTE: You should not employ pop-up windows. They will be blocked by pop-up blocking

software.
