How many API calls am I allowed to make per a time period?

Many developers would like to know ahead of time how many calls they are allowed to make before their app gets throttled.


There are certain API usage plans which are applied to 3rd party applications which use the RingCentral API. These plans can vary depending on a particular API or a users current service plan. But in most cases our servers will reject API requests from a particular application if the request rate exceeds 30 API requests per minute. In this case the client will get an HTTP error with status code 429 too many requests.

That seems like too much of a restriction. How do we increase this?
