Your question is Handling Customer 429 Errors. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
If a customer reports a 429 error and says the API is not working, how would you approach the problem?
Explain how you would clarify the impact, investigate the request pattern, use Chargebee API documentation and response headers, and guide the customer toward a safe resolution. Include how you would communicate during the investigation, distinguish a rate-limit issue from other API failures, and determine when to escalate.
