Rate Limiting/Throttling


The Checkbook API is protected by a number of rate limiting measures to ensure the stability of the system. Not every endpoint is rate limited; however, the endpoints and services deemed to be critical and reliant on performance are limited so as to ensure that each user has fair access to the Checkbook server.

For HTTP APIs, when you request is throttled, you will receive HTTP status code 429. If your request is critical, you should retry your request after a delay. In most cases, the HTTP 429 response code will be accompanied by the Retry-After HTTP header.
