Throttling of API usage is required to protect BlackBerry AtHoc server resources from being over-used, or used in ways that are not intended by BlackBerry AtHoc that can result in slow responsiveness. Throttling limits are applied to overall API usage by any single caller, client, organization, or endpoint. If an API call has reached its throttle limit, the server returns a 429 (Too Many Requests) error.
