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. By default, we evaluate cron expressions in UTC.
If you want to run your schedule in a specific timezone, see the section on Timezones. The following request would create a schedule that will automatically publish the message every minute: 
import { Client } from "@upstash/qstash";

const client = new Client({ token: "<QSTASH_TOKEN>" });
await client.schedules.create({
  destination: "https://example.com",
  cron: "* * * * *",
});
All of the other config options can still be used.
It can take up to 60 seconds for the schedule to be loaded on an active node and triggered for the first time.
You can see and manage your schedules in the Upstash Console.

​
Scheduling to a URL Group

Instead of scheduling a message to a specific URL, you can also create a schedule, that publishes to a URL Group. Simply use either the URL Group name or its id: 
import { Client } from "@upstash/qstash";

const client = new Client({ token: "<QSTASH_TOKEN>" });
await client.schedules.create({
  destination: "urlGroupName",
  cron: "* * * * *",
});

​
Scheduling to a Queue

You can schedule an item to be added to a queue at a specified time. 
curl -XPOST \
import { Client } from "@upstash/qstash";

const client = new Client({ token: "<QSTASH_TOKEN>" });
await client.schedules.create({
  destination: "https://example.com",
  cron: "* * * * *",
  queueName: "yourQueueName",
});

​
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. 
import { Client } from "@upstash/qstash";

const client = new Client({ token: "<QSTASH_TOKEN>" });
await client.schedules.create({
  destination: "https://example.com",
  scheduleId: "existingScheduleId",
  cron: "* * * * *",
});

​
Timezones

By default, cron expressions are evaluated in UTC.
You can specify a different timezone using the CRON_TZ prefix directly inside the cron expression. All IANA timezones are supported. For example, this schedule runs every day at 04:00 AM in New York time: 
import { Client } from "@upstash/qstash";

const client = new Client({ token: "<QSTASH_TOKEN>" });
await client.schedules.create({
  destination: "https://example.com",
  cron: "CRON_TZ=America/New_York 0 4 * * *",
});
