Knock has introduced its schedules API, a tool designed to simplify the process of creating recurring notifications without the need for managing cron jobs. This API allows users to set personalized notification schedules that are aware of recipient time zones, utilizing Knock's scalable infrastructure to handle the execution of these workflows. The API supports complex scheduling rules based on the iCalendar specification, enabling flexibility in defining notifications for different users. The schedules can be managed and debugged through the Knock dashboard, offering visibility into schedule execution and repeat rules. This development aims to relieve engineering teams of the complexities associated with cron infrastructure, ensuring reliable and scalable notification delivery as user bases grow. Additionally, Knock's new support for recipient time zones eliminates the need for manual date and time calculations, automatically adjusting schedules when a recipient's time zone changes.
