API Throttle Limits Update

Starting March 4th, Check will update our default throttle policy in the live production environment from 10,000 requests/hour to 25 requests/second. This rate limit update to the throttle durations is aimed at reducing the severity in hitting rate limits and aims to improve Check API performance overall. The new throttle policy is already active and successfully running without issue across all partners in Sandbox. We have backtested your API usage over the past two months and do not expect this change to impact access. However we recommend you review your own API usage metrics to confirm. Learn more about how to handle rate limits and best practices.

If you would like to opt-in to the new throttle ahead of March 4, or have concerns, please reach out to your technical account manager or create a developer support ticket.
