Cron Jobs

Pulsabase allows you to schedule any edge function using standard cron expression syntax. Scheduled jobs run on the backend — no client needs to be online.

Creating a Cron Job

1. Go to Dashboard → Edge Functions → Cron
2. Click New Cron Job
3. Select the function to invoke
4. Enter a cron expression
5. (Optional) Define a fixed payload to pass to the function on each invocation
6. Save — the job starts immediately

Observability

Every cron execution creates an entry in the Executions log with the following metadata:

• Trigger type: cron
• Cron expression
• Execution status (success / error)
• Duration
• Function input/output

Navigate to Dashboard → Edge Functions → Executions and filter by trigger type cron to monitor scheduled jobs.

Pausing / Resuming

Toggle cron jobs on/off from the Dashboard → Edge Functions → Cron page without deleting them. Paused jobs retain their configuration and history.
