Cronofy Rate Limits

Cronofy advertises unlimited API calls on its paid API tiers and does not publish fixed numeric per-second or per-minute request quotas in its public developer documentation. To protect the platform, Cronofy applies abuse protection and may throttle abnormal traffic, returning HTTP 429 when a client is temporarily rate limited. The batch endpoint caps a single request at 50 sub-requests. Specific numeric limits are not reconciled in this artifact.

Cronofy Rate Limits is the machine-readable rate-limit profile for Cronofy on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring requests.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Scheduling, Calendar, Availability, Booking, and Productivity.
