Using ServiceNow API Explorer to Download Files from URLs

Are you looking to automate the process of downloading files from URLs using ServiceNow’s API Explorer? If so, you’ve come to the right place. In this detailed guide, I’ll walk you through the entire process, from setting up your ServiceNow instance to executing the API call and handling the file download. Let’s dive in!

Understanding the ServiceNow API Explorer

The ServiceNow API Explorer is a powerful tool that allows you to interact with ServiceNow’s APIs. It provides a user-friendly interface to test and execute API calls, making it easier to develop and troubleshoot your integrations. To access the API Explorer, you need to have the appropriate permissions and a ServiceNow instance.

Setting Up Your ServiceNow Instance

Before you can start using the API Explorer, you need to set up your ServiceNow instance. This involves creating a new instance or accessing an existing one. Once you have access, make sure you have the necessary permissions to use the API Explorer. You can check your permissions by navigating to the “My Profile” section and reviewing the roles assigned to your user.

Creating a New Record in ServiceNow

Before you can download a file from a URL, you need to create a new record in ServiceNow. This record will store the URL of the file you want to download. To create a new record, navigate to the appropriate table in ServiceNow and click on “New.” Fill in the required fields, such as the file URL, and save the record.

Executing the API Call

Now that you have a record with the file URL, it’s time to execute the API call. The API call will retrieve the file from the URL and save it to your ServiceNow instance. To do this, open the API Explorer and select the appropriate API endpoint. In this case, you’ll need to use the “cmdb_ci_file” endpoint.

Here’s an example of the API call you’ll need to make:

GET /api/now/table/cmdb_ci_file?sys_id=YOUR_RECORD_ID

In this example, “YOUR_RECORD_ID” is the ID of the record you created earlier. The API call will return the file metadata, including the file URL.

Handling the File Download

Once you have the file metadata, you can proceed to download the file. To do this, you’ll need to make another API call to the file URL. Here’s an example of the API call you’ll need to make:

GET /api/now/file?sys_id=YOUR_RECORD_ID

In this example, “YOUR_RECORD_ID” is the ID of the record you created earlier. The API call will return the file content, which you can then save to your local machine.

Example Code

Here’s an example of how you can write a script to download a file from a URL using ServiceNow’s API Explorer:

import requestsdef download_file(url, file_name):    response = requests.get(url)    if response.status_code == 200:        with open(file_name, 'wb') as f:            f.write(response.content)        print(f"File {file_name} downloaded successfully.")    else:        print(f"Failed to download file. Status code: {response.status_code}") Replace YOUR_RECORD_ID with the actual record IDfile_url = "https://your-service-now-instance.com/api/now/file?sys_id=YOUR_RECORD_ID"file_name = "downloaded_file.txt"download_file(file_url, file_name)

Conclusion

Using ServiceNow’s API Explorer to download files from URLs is a straightforward process. By following the steps outlined in this guide, you can automate the file download process and integrate it into your ServiceNow workflows. Whether you’re looking to streamline your file management or create custom integrations, the API Explorer is a valuable tool to have in your arsenal.
