Job Schedules
Payload's schedule
property lets you enqueue Jobs regularly according to a cron schedule - daily, weekly, hourly, or any custom interval. This is ideal for tasks or workflows that must repeat automatically and without manual intervention.
Scheduling Jobs differs significantly from running them:
- Queueing: Scheduling only creates (enqueues) the Job according to your cron expression. It does not immediately execute any business logic.
- Running: Execution happens separately through your Jobs runner - such as autorun, or manual invocation using
payload.jobs.run()
or thepayload-jobs/run
endpoint.
Use the schedule
property specifically when you have recurring tasks or workflows. To enqueue a single Job to run once in the future, use the waitUntil
property instead.
Example use cases
Regular emails or notifications
Send nightly digests, weekly newsletters, or hourly updates.
Batch processing during off-hours
Process analytics data or rebuild static sites during low-traffic times.
Periodic data synchronization
Regularly push or pull updates to or from external APIs.
Scheduler modes (jobs.scheduler
)
Payload supports two scheduler modes suitable for different deployment environments:
Mode | When to use | Behaviour |
---|---|---|
| Long-running Node environments | Initializes all cron schedules on Payload startup using Croner, regularly evaluating and enqueueing Jobs on time. |
| Ephemeral / serverless environments (Vercel, Netlify, AWS Lambda) | No automatic scheduling occurs. You must explicitly invoke scheduling using |
Example configuration:
Defining schedules on Tasks or Workflows
Schedules are defined using the schedule
property:
Example schedule
The following example demonstrates scheduling a Job to enqueue every day at midnight:
This configuration only queues the Job - it does not execute it immediately. To actually run the queued Job, you configure autorun in your Payload config (note that autorun should not be used on serverless platforms):
That way, Payload's scheduler will automatically enqueue the job into the nightly
queue every day at midnight. The autorun configuration will check the nightly
queue every minute and execute any Jobs that are due to run.
Scheduling lifecycle
Here's how the scheduling process operates in detail:
- Cron evaluation: Payload (or your external trigger in
manual
mode) identifies which schedules are due to run. To do that, it will read thepayload-jobs-stats
global which contains information about the last time each scheduled task or workflow was run. - BeforeSchedule hook:
- The default beforeSchedule hook checks how many active or runnable jobs of the same type that have been queued by the scheduling system currently exist. If such a job exists, it will skip scheduling a new one.
- You can provide your own
beforeSchedule
hook to customize this behavior. For example, you might want to allow multiple overlapping Jobs or dynamically set the Job input data.
- Enqueue Job: Payload queues up a new job. This job will have
waitUntil
set to the next scheduled time based on the cron expression. - AfterSchedule hook:
- The default afterSchedule hook updates the
payload-jobs-stats
global metadata with the last scheduled time for the Job. - You can provide your own afterSchedule hook to it for custom logging, metrics, or other post-scheduling actions.
Customizing concurrency and input (Advanced)
You may want more control over concurrency or dynamically set Job inputs at scheduling time. For instance, allowing multiple overlapping Jobs to be scheduled, even if a previously scheduled job has not completed yet, or preparing dynamic data to pass to your Job handler:
This allows fine-grained control over how many Jobs can run simultaneously and provides dynamically computed input values each time a Job is scheduled.
Scheduling in serverless environments
On serverless platforms, scheduling must be triggered externally since Payload does not automatically run cron schedules in ephemeral environments. You have two main ways to trigger scheduling manually:
- Invoke via Payload's API:
payload.jobs.handleSchedules()
- Use the REST API endpoint:
/api/payload-jobs/handleSchedules
- Set the
run
REST API to trigger scheduling:POST /api/payload-jobs/run?handleSchedules=true
For example, on Vercel, you can set up a Vercel Cron to regularly trigger scheduling:
- Vercel Cron Job: Configure Vercel Cron to periodically call
GET /api/payload-jobs/handleSchedules
. If you already have vercel cron set up for auto-running, you can also append?handleSchedules=true
to therun
endpoint to trigger scheduling.
Once Jobs are queued, their execution depends entirely on your configured runner setup (e.g., autorun, or manual invocation).
