Google Cloud Scheduler Cron Job

By: O. Wolfson

Cron jobs are a commonly used tool for scheduling repetitive tasks. Essentially, a cron job is a scheduled task that runs at regular intervals on a server. One common use case for cron jobs is to send HTTP requests to API endpoints, which can help automate various processes and make it easier to manage data.

When you hit an API endpoint, you are essentially making an HTTP request to a specific URL that triggers a particular action or retrieves data. Depending on the type of API and the request being made, different types of HTTP requests may be used, such as GET, POST, PUT, or DELETE. In this particular example, the API endpoint updates the date on a document in MongoDB Atlas. By hitting the API endpoint with an HTTP request using Google Cloud Scheduler, we can automate the process of updating the date on the document in MongoDB Atlas. This could be necessary if the date needs to be updated on a regular basis automatically.

Google Cloud Scheduler is a tool that makes it easy to schedule and manage cron jobs in the cloud. With Google Cloud Scheduler, you can create jobs that run at regular intervals and trigger HTTP requests to specific API endpoints. This can help streamline workflows and automate tasks, making it easier to manage data and improve overall efficiency. In this article, we will explore how to use Google Cloud Scheduler to schedule cron jobs and make HTTP requests to API endpoints.

  • A project set up in Google Cloud

How to Create a Google Cloud Scheduler Job

To use Google Cloud Scheduler to run cron jobs and specifically how to run an HTTP request to an API route:

  1. First, make sure you have a Google Cloud Platform account set up and have created a project to work with. If you haven't done this already, you can follow the steps provided on the Google Cloud Platform website to get started.

  2. Once you have your project set up, navigate to the Google Cloud Scheduler console by clicking on the following link:

  3. Click on the "Create job" button to create a new job.

  4. Give your job a name, description, and frequency. For example, if you want to run your job every day at 12:00 PM, you could set the frequency to "0 12 * * *". You can also choose the time zone you want to use.

  5. In the "Target" section, choose "HTTP" as the target type.

  6. In the "URL" field, enter the URL of the API route you want to call. For example, if your API route is "", enter that URL here.

  7. Choose the HTTP method you want to use. In this case, you would select "POST" as you want to update the document in your Mongo database.

  8. If you need to provide any headers or a request body, you can add those in the "Headers" and "Body" sections, respectively.

  9. If your API requires authentication, you can provide your credentials in the "Authorization" section.

  10. Click on the "Create" button to create your job.

Your job is now set up to run at the frequency you specified, and it will call your API route at the specified URL with the specified HTTP method, headers, body, and authentication credentials. You can check the status of your job in the Google Cloud Scheduler console and make any necessary changes or updates as needed.
