How is an API key formed in Stripe?

• A. A key and mode combined makes the API key.
• B. A secret and public key combined.
• C. A product and mode combined.
• D. A customer ID and mode combined.

Answer: (A)

In Stripe, an API key is a single credential that encodes both what kind of key it is and which environment you’re targeting. The mode is part of the key itself through its prefix, such as sk_test_... or sk_live_... for secret keys, and pk_test_... or pk_live_... for publishable keys. That means the API key you use already combines the credential type and the mode—you don’t assemble separate pieces yourself. This is why the correct idea is that a key and mode combined form the API key. Other options would imply combining two separate identifiers (like secret and public keys) or unrelated identifiers (product IDs, customer IDs), which isn’t how API keys are constructed.
