Scheduled actions

Scheduled actions manage background tasks related to WooCommerce order notifications and payment processing. Gaining a clear understanding of these actions can help your store run more efficiently, and prevent issues — such as missed order updates or delayed customer emails.

You can find all scheduled actions in your store’s WP Admin dashboard under WooCommerce > Status > Scheduled Actions.

Before explaining how scheduled actions work, it is helpful to understand both cron and WP-Cron.

Cron is a time-based task scheduling tool commonly used to automate maintenance tasks on servers. WP-Cron is WordPress’s way of handling scheduled tasks.

WP-Cron runs whenever someone visits your website, initiating when a page is requested. It allows WordPress to execute scheduled tasks in the background, minimizing the impact on page load times or site performance. WP-Cron also checks for theme or plugin updates, sends emails, and schedules sale prices in WooCommerce.

Because WP-Cron relies on site traffic, scheduled tasks may be delayed if there is low traffic to your store. Conversely, excessively high traffic could cause performance issues.

WP Crontrol is a free, helpful tool for viewing, triggering, and troubleshooting cron events.

Action Scheduler is a scalable, traceable job queue for handling large sets of tasks within WordPress. It’s widely used to manage millions of WooCommerce Subscriptions payments, WooCommerce webhooks, and events or emails for other extensions/plugins.

Action Scheduler sends tasks in batches of 20, preventing PHP memory exhaustion. It can handle multiple batches simultaneously, processing up to five queues at once.

Action Scheduler uses a custom WordPress post type — scheduled-action — to store details such as the hook name, arguments, and the scheduled time for future tasks. It runs by attaching itself as a callback to the action_scheduler_run_schedule hook, which is triggered using WordPress’s built-in WP-Cron.

Essentially, WP-Cron activates Action Scheduler.

Once triggered, Action Scheduler looks for scheduled-action posts that are ready to run. By default, it relies on WP-Cron, which means it is also dependent on site traffic. You can also set up custom server-side cron jobs to run WP-Cron independently and bypass traffic dependency, making it more reliable.

As mentioned above, you can find scheduled actions in your store’s WP Admin dashboard under WooCommerce > Status > Scheduled Actions.

From here you can:

• Run a pending action.
• View scheduled actions with a specific status (such as all in-progress actions).
• View log entries for failed actions.
• Search scheduled actions by hook name, scheduled date, or group name.
