Hello,
Thank you for raising the question.

You'll receive an HTTP status code 429 response under these circumstances:

• Exceeding the daily request limit for a store in the Free tier.
• Temporary throttling due to a high request rate for a store in the Standard tier.
• Excessive bandwidth usage.
• Attempting to create or modify a key when the storage quote is exceeded.
• Check the body of the 429 response for the specific reason why the request failed.
