Visa 3DS Challenge Test Card Numbers
Visa · 3DS Challenge: 3DS challenge requires customer authentication. MockCard includes next_action.redirect_to_url on the payment_intent, matching Stripe 3DS patterns.
Visa test PANs use standard 16-digit formatting. MockCard returns Luhn-valid numbers and a signed payment_intent webhook — ideal for Stripe-style integrations and CI pipelines.
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.
