Rate Limits

Rate limits are applied per account and enforced at the API gateway level. All limits are measured in requests per minute with an additional burst capacity for short spikes.
Burst capacity allows you to exceed the steady-state rate limit for a short period. For example, an endpoint with 50 req/min and burst 3 means you can fire up to 3 requests in rapid succession before the 50 req/min cap is enforced.

Monthly Analytics Quotas

Analytics endpoints are subject to a monthly call quota in addition to the per-minute rate limit. Quotas reset automatically on the 1st of each calendar month.
Your current usage and remaining calls are visible in the Sandbox from the user menu (top right).

Need higher limits?

Default limits work for most use cases, but if your project requires more — more analytics calls, more participants, or a larger team — we can adjust them for you.
