Cron Jobs are a powerful tool for automating time-based tasks on a server. These tasks are scheduled to run at specific intervals, which helps to ensure repetitive processes are executed without the need for manual intervention. By automating tasks like sending out email notifications, updating databases, or generating reports, these jobs can save you time and streamline your workflow.

Think of them as a personal assistant that handles the mundane, repetitive tasks for you so that you can focus on more important work. They’re a great way to keep your website running smoothly without constantly monitoring it.

So if you’re looking to automate specific tasks on your website, Cron Jobs are definitely worth considering. They’re easy to set up and can save you a lot of time and hassle in the long run.

What about WordPress Cron Jobs

But did you know that WordPress has its version of Cron Jobs called “WordPress Cron Jobs” or “WP-Cron”? This powerful system allows you to schedule and automate tasks within your WordPress website, like publishing scheduled posts, checking for updates, or sending out email notifications.

In the next section, we’ll dive deeper into Cron Jobs and explore how they differ from WordPress Cron Jobs. By understanding the differences between these two types of task schedulers, you can choose the one that’s right for your specific needs.

Understanding Cron Jobs

Cron Jobs are automated tasks that run on a predefined schedule in Unix-based systems (E.g. your server on which your website is hosted). They’re designed to perform repetitive tasks automatically without manual intervention. By automating these tasks, these automated jobs can save time and resources while ensuring that essential maintenance and updates are completed consistently.

How do they work?

Cron Jobs are managed by a service (daemon) called “cron,” which runs in the background and is responsible for launching scheduled tasks. The schedule for each task is defined in a particular file called the “crontab” (short for “cron table”). The crontab file contains a list of commands and their corresponding schedules, instructing the cron daemon when to execute each command.

The good news is that you don’t have to worry about the complex logic behind Cron Jobs (most of the time). Most server hosts provide a simple interface that allows you to define a PHP file that can be called by a Cron Job. From there, you can run additional logic within that file, which will be executed on your defined schedule.

This means that you don’t need to have extensive programming knowledge to use them effectively. With the right tools and resources, you can easily set up and manage your them to ensure your website runs automated around the clock.

WordPress Cron Jobs

While standard Cron Jobs are part of Unix-based systems and rely on the server’s clock, WordPress Cron Jobs are built into the WordPress core and don’t depend on the server’s time. Instead, they’re triggered by website activity, such as user visits, and are sometimes referred to as “pseudo-cron jobs.”

How WordPress Cron Jobs work

  1. WP-Cron.php
    The WP-Cron system is managed through a file called “wp-cron.php,” which is responsible for scheduling and executing tasks within WordPress. When a visitor accesses your website, WordPress checks if there are any scheduled tasks due for execution. If a task is due, WordPress executes it by making an HTTP request to the “wp-cron.php” file.
  2. Scheduling events
    WordPress Cron Jobs can be scheduled through the WordPress API using functions like wp_schedule_event(), wp_schedule_single_event(), and wp_clear_scheduled_hook(). These functions allow developers to create, modify, and remove scheduled tasks within WordPress.
  3. Execution of scheduled events
    When it’s time to execute a scheduled event, WordPress runs the associated function or action hook. Developers can register custom functions or hooks to be executed at specified intervals, such as hourly, twice daily, or daily.

Pros and cons of using WordPress Cron Jobs

While this powerful tool can help automate tasks and streamline workflows, it also comes with some potential drawbacks that you should be aware of. Here’s what we think of it.


  • Easy to set up and use within the WordPress environment
  • No need for server access or expertise in Unix-based systems
  • Convenient for small-scale tasks and low-traffic websites


  • Not as precise as server-based Cron Jobs since execution depends on website activity
  • It may not be suitable for high-traffic websites or tasks requiring exact timing
  • It can cause performance issues if not properly managed and optimized

WP Webhooks and Cron

WP Webhooks is a powerful plugin for WordPress that enables the integration of web applications using webhooks and automation workflows. Whether you’re a blogger looking to automate your social media posting, an e-commerce store owner looking to streamline your order processing, or a marketer looking to track your website analytics, WP Webhooks has something for you. With its user-friendly interface and powerful automation features, WP Webhooks is a must-have tool for any serious WordPress user.

Cron Scheduler integration in WP Webhooks

The WP Webhooks plugin comes with a built-in Cron Scheduler integration, allowing you to harness the power of Cron Jobs directly within your WordPress website. The integration includes two triggers:

  1. Cron job executed trigger
    This trigger integrates with a standard server-based Cron Job. When the the job runs, the trigger is activated, and any associated actions will be executed.
  2. WordPress cron job executes trigger
    This trigger integrates with the WordPress Cron Job system. When a WordPress job is executed, the trigger is activated, and any associated actions will be executed.

How to use WP Webhooks with Cron Jobs

  1. Setting up WP Webhooks and Cron Scheduler
    To get started with WP Webhooks and Cron Scheduler, first install and activate the WP Webhooks plugin on your WordPress website. Once activated, navigate to the plugin Integrations page and activate the Cron Scheduler.
  2. Configuring the trigger
    Head into a Flow of your choice or add a webhook URL to the “Webhooks” tab trigger. This entirely depends if you want to create a Workflow (To execute multiple actions consecutively within WordPress), or to use a Webhook (Send a single request each time the trigger is fired).
  3. Implementing your custom automation flows
    With configured triggers, you can now create custom automation flows by connecting your WordPress website to external services or applications. This can include sending data to other platforms, receiving data from external sources, or even triggering custom scripts to run on your server. The possibilities are endless, allowing you to automate tasks and streamline your website management processes.

This can keep your site fresh and up-to-date without manual intervention.

Scheduling regular backups

Keeping your website data safe is crucial. By combining WP Webhooks with Cron Jobs, you can schedule regular backups of your WordPress site. Configure a job to trigger a webhook that initiates a backup process with your preferred backup service or plugin. This ensures that your site’s data is consistently backed up and protected from potential data loss.
