Rate Limits

This page lists the rate limits for each API endpoint in both Sandbox and Production environments.

Rate Limit Dimensions

Dimension	Description
Per app_key	Most endpoints are rate-limited at the application level. All requests sharing the same app_key count toward a single quota.
Per User	Connect API endpoints are rate-limited per authorized user (account_id).
Per Endpoint	Each endpoint has its own independent rate limit counter. Hitting the limit on one endpoint does not affect others.

Rate Limit Exceeded Behavior

When a rate limit is exceeded:

• The API returns HTTP status 429 Too Many Requests.
• The request is rejected — no partial processing occurs.

caution

Repeatedly exceeding rate limits may result in temporary IP-level blocking. Ensure your application respects the limits and implements proper retry logic.

Rate Limit Format

Limits are expressed as N/Ts where N is the maximum number of requests and T is the time window in seconds. For example, 10/30s means 10 requests per 30-second window.

• Sandbox limits are typically lower than Production to encourage efficient integration patterns during development.
• Contact your account manager if your use case requires higher limits.
