Yes. In the test environment, rate limits are applied, so if a certain TPS is exceeded, a `Rate limit` error (429) will occur.
Also, since the test environment is a shared environment, the conditions under which the rate limit occurs (time periods when it is more likely to occur and the number of requests) vary depending on the usage situation of other merchants.
Additionally, because the test environment is shared among all merchants, please do not conduct performance or load testing.
Note: The performance limit (TPS) of PayPay is not disclosed, so we cannot provide an answer even if you inquire.
1. If a 429 error occurs in the test environment
1. Check whether you are sending a large number of requests in a short period of time.
2. Reduce the request interval and the number of parallel requests, then retry.
3. Wait some time before retrying.
2. About the production environment
The production environment is designed to handle a large number of requests even during busy periods.
