Rate Limits

The purpose of the rate limit is to ensure a high quality of QuickBlox service across all QuickBlox accounts, by limiting the number of API requests that an account can produce per second.

If you go over these limits when using REST based APIs, QuickBlox will start returning a HTTP 429 Too Many Requests error.
