Which Stripe API key is used on the client-side to tokenize payment information?

• A. Publishable Key pk_
• B. Secret Key sk_
• C. Test Mode _test_
• D. Live Mode _live_

Answer: (A)

Tokenizing payment information in the browser is done with Stripe.js using a publishable key. This key is safe to expose in client code and lets Stripe tokenize card details, returning a token or payment method ID that you can send to your server for processing. The secret key is intended for server-side use only and must remain confidential; it signs actions like creating charges or confirming payment intents and should never be exposed in the client. Environment indicators (test vs live) relate to which set of keys you use, but they don’t change the fact that client-side tokenization uses the publishable key.
