What are API Rate Limits?

KB: 0066

API rate limit is the number of requests that a specific API or user can make within a given time frame. All API's requests are subject to rate limits. When this rate limit is exceeded, the requests that are done or the amount of calls using the said API or user may fail and be throttled.
