1Rate limits #

Limits apply per endpoint and per Client. They exist to protect platform stability, not to restrict your use. If you approach a limit in the normal course of business, we raise it where we reasonably can rather than throttle.

Limit	Default	Notes
Sustained	3,600 requests / hour	Per endpoint, per Client
Burst	100 requests / 10 seconds	Short spikes above the sustained rate
Increases	On request	Email api@callplaybook.com with your expected volume

Do not work around limits with multiple credential sets or distributed requests. See API Terms, Section 6 (Rate Limits and Fair Use).
