An authentication error occurred. Most commonly, the request had a missing, malformed, or otherwise invalid Authorization header.

Your application should monitor responses for 429 RATE_LIMITED errors and use a retry mechanism with an exponential backoff schedule to resend the requests at an increasingly slower rate. It is also a good practice to use a randomized delay (jitter) in your retry schedule.

An error occurred while processing a payment method. Most commonly, the details of the payment method were invalid (such as a card's CVV or expiration date).

An error occurred while attempting to process a refund.
