Schedules

In addition to sending a message once, you can create a schedule, and we will publish the message in the given period. To create a schedule, you simply need to add the Upstash-Cron header to your publish request.

Schedules can be configured using cron expressions. crontab.guru is a great tool for understanding and creating cron expressions.

We use UTC as timezone when evaluating cron expressions.

The following request would create a schedule that will automatically publish the message every minute:

All of the other config options can still be used.

You can see and manage your schedules in the Upstash Console.

​

Scheduling to a Queue

You can schedule an item to be added to a queue at a specified time.

Overwriting an existing schedule

You can pass scheduleId explicitly to overwrite an existing schedule or just simply create the schedule with the given schedule id.
