Does the rate limit apply to all API in an API group or for a single API endpoint?
Rate Limits is per API group. If your app is accessing multiple endpoints in the same API group, the requests are cumulative across endpoints. For example, if your app as a limit of 10 requests per minute for
Heavy APIs and you make 5 each requests across 2
Heavy endpoints, you will be at your 10 requests per minute limit.
What happens if my app exceeds its rate limit?
If you exceed the API rate limit, the server will return the 429 HTTP error status code indicating Too Many Requests. This means that the client is being throttled by the server due to high request rate. The
Retry-After response header will specify the number of seconds that should elapse before your app can make requests again.
