Rate limits
Sendbird applications are rate-limited to ensure the best experience for users. If you exceed a rate limit, Sendbird server will return an error message that includes the encountered rate limit as well as how long you should wait before retrying.
Note : Sendbird organizations created after May 28, 2020, 00:00:00 UTC are automatically rate-limited, while those created before this date will be given sufficient time to adjust their applications before rate limits apply. Go to the Settings > Application > General on the Sendbird Dashboard to see which rate limits your organizations are subject to. If you need a higher rate limit for API requests, contact our sales team for further assistance.
