Scheduled jobs are an integral part of any modern web application, enabling developers to automate tasks, run background processes, and ensure that critical operations are executed at specific times. Laravel provides a robust mechanism for managing scheduled tasks through its built-in scheduler. In this blog post, we will explore how to use the onSuccess and onFailure methods to handle success and failure scenarios for scheduled jobs in Laravel.

Understanding scheduled jobs in Laravel

Before diving into the specifics of handling success and failure, let's briefly review how scheduled jobs work in Laravel. Laravel's scheduler allows you to define tasks to run at specified intervals using the schedule method within the App\Console\Kernel class.

Here's a basic example of scheduling a job to run every minute:

1// App\Console\Kernel.php
3protected function schedule(Schedule $schedule)
5    $schedule->job(new MyScheduledJob())->everyMinute();

In the example above, MyScheduledJob is a class that implements the ShouldQueue interface, indicating that it can be queued for asynchronous execution.

onSuccess: handling success

The onSuccess method is a powerful tool for handling tasks that complete successfully. It allows you to define what should happen after a job has executed without any issues. This is particularly useful when you want to chain multiple jobs together or perform specific actions upon successful completion.

Here's how to use onSuccess:

1$schedule->job(new MyScheduledJob())
2    ->everyMinute()
3    ->onSuccess(function () {
4        // Code to execute when the job succeeds
5    });

For instance, you can send a notification, update database records, or trigger another job that relies on the success of the initial task.

onFailure: handling errors

Handling failures is equally important when working with scheduled jobs. Laravel provides the onFailure method to help you gracefully manage errors or exceptions that occur during job execution.

To use onFailure, you can pass a closure that defines what should happen when a job fails:

1$schedule->job(new MyScheduledJob())
2    ->everyMinute()
3    ->onFailure(function () {
4        // Code to execute when the job fails
5    });

Common use cases for onFailure include logging errors, sending alerts to administrators, or implementing a retry mechanism for failed jobs.

Combining onSuccess and onFailure

In many scenarios, you may want to handle both success and failure events for a scheduled job. Laravel allows you to combine onSuccess and onFailure methods to specify actions for both outcomes:

1$schedule->job(new MyScheduledJob())
2    ->everyMinute()
3    ->onSuccess(function () {
4        // Code to execute on success
5    })
6    ->onFailure(function () {
7        // Code to execute on failure
8    });

By using these methods in conjunction, you can create a robust and flexible system for managing scheduled jobs in Laravel.


Scheduled jobs are a vital part of Laravel's arsenal for automating tasks and ensuring the smooth operation of your web application. The onSuccess and onFailure methods provide a convenient way to handle success and failure scenarios, allowing you to build robust, error-tolerant, and responsive systems.

Whether you need to send notifications, log errors, or take other actions based on the outcome of a job, these methods empower you to do so with ease. Incorporate them into your Laravel projects to enhance the reliability and maintainability of your scheduled tasks.
