Words to know
- Test / sandbox mode
- A practice version of a payment system. You can “pay” with test cards to try your checkout, but no real money moves.
- 3D Secure (3DS)
- The extra step where your bank asks you to confirm a payment (an OTP or app approval). It protects against stolen cards.
- Decline code
- A short reason the bank gives when it refuses a payment, like “insufficient_funds” (not enough money).
