MasterCard 3DS Challenge Test Card Numbers
MasterCard · 3DS Challenge: 3DS challenge requires customer authentication. MockCard includes next_action.redirect_to_url on the payment_intent, matching Stripe 3DS patterns.
Mastercard test cards use 16-digit BIN ranges distinct from Visa. Use this page when your checkout detects network brand or routes MC-specific decline handling.
When to use: Test redirect flows, return_url handling, and abandonment when the user closes the challenge window.
CI tip: Combine with the chaos 3ds_abandoned scenario on Pro for abandonment after challenge starts.
Typical decline_code in webhook payloads: authentication_required.
