What is test mode (API Key)?

• A. Mode used as you build your app; payments are processed.
• B. Mode used to simulate production transactions.
• C. Mode used as you build your app. Payments are not processed.
• D. Mode used to enable live payments.

Answer: (C)

Test mode uses a separate set of API keys so you can develop and test your Stripe integration without moving real money. In this mode you can simulate payments using Stripe’s test card numbers, verify webhooks, and test flows end-to-end, but no actual funds are charged. That’s why the description “mode used as you build your app. Payments are not processed” is the best fit. It’s distinct from live mode, which enables real payments, and from descriptions that imply real processing or only vague simulation.
