How to derive a direct link to a file from the link to the download page?

Question

I have publicly accessible files in Salesforce (accessible by anyone, even without a Salesforce license), which can be accessed via URLs such as this:

https://XXXXXXXX.my.salesforce.com/sfc/p/#58000000Og0w/a/4H000001BDWe/FG3cuoiwxYaI_SGe9ZYC9swLPnX.88vSoqwtw9EgRH8

However, this is a page that displays the file with a download link. I would like to have a link to the file itself, without any HTML wrapping it. With googling I found that there are links like

https://<YOUR_SFDC_BASE_URL>/sfc/servlet.shepherd/version/download/068XXXXXXXXXXXX

that should do that, but they require a Content Version record Id, which always starts with 068. As you can see, the original URL does not contain something like that. Is there a way to programmatically derive the second URL from the first URL?

UPDATE: Yrc Shk suggests to use the DistributionPublicUrl object. Creating such an object from a ContentVersion gives you several URLs:

• ContentDownloadUrl
• DistributionPublicUrl
• PdfDownloadUrl

Where DistributionPublicUrl is the URL that I started with, the page that allows you to download a file. The other two URLs appear to be the ones linked to the two Download buttons on that page.

But what I am really looking for, I'll say it more carefully now, is a URL to a page that displays just the file, without an HTML wrapper, without automatic downloading (a user might choose to download using the browser).

Answer 1

This can be done through ContentDownloadUrl, not to be confused with DistributionPublicUrl. The container URL you see is the DistributionPublicUrl, however the actual file URL can be found in ContentDownloadUrl.

You can read how to generate the URL in the below blogpost -
