MasterCard Success Test Card Numbers
MasterCard · Success: Approved charges are the baseline every payment suite needs. This scenario returns a succeeded payment_intent and fires payment_intent.succeeded to your webhook_url when configured.
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: Use after deploys to confirm order fulfilment, inventory decrement, and email receipts still run when status is succeeded.
CI tip: Assert webhook type payment_intent.succeeded and that your idempotency key handles duplicate delivery if simulate_race is enabled on Pro.
Webhook event: payment_intent.succeeded with signed X-MockCard-Signature header.
