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.
Rate limits apply to the 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 or a group channel. The following table lists the default rate limits per user.
|SDK method||Calls per second||Calls per minute|
