Hi, I have enabled 3D Secure functionality from SuiteCommerce Configuration. But I am unable to figure out why this is not working (seems I am missing something). From what I understand a credit card authentication modal/page should appear before I place order during checkout. But nothing has changed, the checkout process is working as it normally does. Please can you guide me what I am missing/what are the correct steps I should follow to view the cc authentication page before placing order?

3D Secure turned on in SC configuration, and also "Payer Authentication" ticked in the payment processing profile.

Thanks a lot. One more thing does this also work for Sandbox or Demo instances of NetSuite?

Can only comment for Cybersource (Legacy) - it works in sandbox and release preview accounts. You'll need to use a Cybersource test key file in the payment processing profile and a card number which is specifically for 3DS testing

Thanks @Dominic B. Will give this a go.
