HTTP-Triggered File Download for PDFs

This workflow enables seamless file downloads directly from an incoming HTTP GET request. It starts with a webhook node listening on the '/download-pdf' path. Upon receiving the request, it uses an HTTP Request node to fetch a binary file, such as a PDF from a specified URL. Finally, the Respond to Webhook node sends the file back with a Content-Disposition header set to 'attachment', forcing the browser to download it with a custom filename that includes the current date (e.g., 'my_document_2023-10-05.pdf').

The key benefit is preserving the current page while initiating the download, ideal for web applications. It avoids replacing page content, enhancing user experience in scenarios like form submissions or data exports.

Use cases include finance applications for downloading reports or invoices at the end of processes, e-commerce for order PDFs, or any web-integrated system needing on-demand file serving. It's lightweight, requiring no database or complex logic, and easily customizable by changing the fetch URL or filename template.
