Too Many Requests
The API returns error if there are accesses that greatly exceed the ordinary load to the server within a certain period of time for an application. This limit is set per application under an agreement with Kii.
The limit is high enough for ordinary changes in the operational load. However, if active users simultaneously send a request on the same time or event, it could cause an API error.
If the number of API calls exceeds the limit, each API responds with HTTP status code 429. This error does not include JSON data for detailed information.
To avoid congestion, do not implement a retry process for the request.
