In a world where PDF documents reign supreme for sharing and preserving content, the need to download them efficiently is a common task. Whether it's research papers, user manuals, or reports, we all find ourselves needing to gather PDFs from the vast expanse of the internet. However, manually downloading each PDF file can quickly become a tedious and time-consuming process.

One such remarkable feature in our RPA tool is the browser package—a comprehensive suite comprising 23 meticulously designed nodes. From opening browsers to capturing screenshots, these nodes offer a versatile set of capabilities that can revolutionize the way we interact with web content.

In this blog post, we will explain how to automate the process of downloading PDFs using Browser Automation with Robomotion.

About Browser Package

The browser package refers to a collection of nodes that are specifically designed to interact with web browsers. These nodes enable automation of web-based tasks and processes by providing a set of actions that mimic human interactions with a browser.

The browser package consists of 23 nodes, each representing a specific action that can be performed within a web browser. These actions range from basic functions like opening and closing browsers, clicking on elements, and navigating forward or backward, to more advanced operations like capturing screenshots, handling alerts, and even executing custom scripts within the browser environment.

Flow Steps

  1. ‘Inject’ node is used to initialize the flow.
  2. The "Config" function node contains JavaScript code designed to define variables.

Function Node Named “Config” Code-Block:

//User Directory Path to save Chrome settings 
msg.user_directory_path = "YourUserDataDirFolderPath";
//Download Path to save PDF files
msg.download_path = "YourDownloadFolderPath";
//Give a url for the pdf file to download
msg.url = "";
return msg;
  1. During the initial run, you should establish a connection to the "Save Settings" sub-flow node, which comprises four individual nodes:
