Is there any free file-sharing site that lets users upload a file that allows direct downloads of the files uploaded just with a simple link? I know that a similar question has been asked (like A web storage site with direct file link), but let me explain the technical details why those solutions do not work for my specific use case.
My use case is that I need to upload simple files (specifically CSV, PDF, Excel spreadsheet or Microsoft Word) for the automatic population of FAQ topics by the Microsoft Power Virtual Agent (PVA) chatbot. The PVA interface allows developers to point to an https resource (either a web page or one of the above-mentioned file types) and it uses natural language processing to automatically convert the resource into its custom chatbot format.
For some bizarre reason, the PVA interface does not allow direct uploads of files. Developers may only point to either a web page or a file that is directly accessible via an https address. I need to upload Excel spreadsheets (in XLSX format) to train the chatbots.
I initially tried to share the file with file syncing services (specifically, Dropbox and OneDrive). However, I had trouble with both because the PVA file upload interface requires a link that directly downloads a file whereas those services lead to a page that views these files on their servers. After a lot of searching and trial and error, I have finally figured out how to generate direct download links from Dropbox. So, I can get this to work in my own personal situation. I also have a personal web server and I was able to upload the file there and PVA recognized it. However, I was unable to get this to work with OneDrive for Business despite many suggested attempts I tried. (Ironic, considering that both PVA and OneDrive are Microsoft applications.)
My problem now is that I want to train other users in my organization to use PVA and this upload feature is an important necessity for many of them. My organization uses OneDrive, so that would have been the easiest solution if I could have gotten it to work.
I have searched the Web and found many temporary file upload services, but all of them go to a page that then requires a subsequent click for downloading. (I understand; they have to fund their free service with ads.) So, I have not found anything that works.
So, my question is this: is there any free file-sharing site that lets users upload a file that allows direct downloads of the files uploaded just with a simple link? The only links that work with PVA must not lead to a user-viewable page that then requires the user to click on a link to download, and the direct link must not use any URL query options (e.g., "?download=1").
