Rate limits

Sendbird applications are rate-limited to ensure the best experience for all users. The rate limits vary depending on your plan. You can find which rate limits your organization is subject to under Organization settings > General on the Sendbird Dashboard. If you exceed the rate limits, Sendbird server will return an error response. If you need a higher rate limit for API requests, contact our sales team for further assistance.

Note : Sendbird organizations created after May 28, 2020, 00:00:00 UTC are automatically rate-limited, while those created before this date will have sufficient time to adjust their applications before rate limits apply.
