Rate limits

Copy link

Sendbird applications are rate-limited to ensure the best experience for users. If you exceed a rate limit, the Sendbird server returns 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 are given sufficient time to adjust their applications before rate limits apply. Go to Settings > Application > General on 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.
