Limits

Limits in SendGrid are calculated using the leaky bucket algorithm. All requests that are made after rate limits have been exceeded are throttled and an HTTP 429 Too Many Requests error is returned. Requests succeed again after enough requests have emptied out of the bucket.

• Cyera supports requests throttling to stay within 70-80% of specified service rate limits.
• Cyera processes API responses with HTTP 429 status to interrupt requests, waiting and retrying (using an exponential backoff strategy).
