Rate limits

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.

To prevent abnormal user activity, Sendbird application has the following default limits on the number of messages per second which a user can send and a channel can display.

Rate limits apply to SDK methods associated with objects including channel, user, message objects, and more. For example, a user can send up to five messages per second to an open channel or a group channel. The following table lists the default rate limits per user.

Several real-time events taking place in client apps are rate-limited in order to maintain stable and efficient operation. The following table lists the default rate limits for those events.

When a request is rate-limited, a RateLimitExceeded (500910) or TooManyMessages (900200) error is returned. See the error codes page for more information.
