API to get content hash of shared file link

Hi.   Is there an API endpoint to get the content hash of a file received as a shared link?   Where the shared link is to a folder, it's possible with:   sharing/get_shared_link_metadata { "url...

No, unfortunately API doesn't offer a way to get the content hash for a file given just a shared link to the file itself from another account, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.

    Thanks Greg.

     

    It would be very valuable to be able to retrieve this information from the API. As I mentioned, currently we have to download everything twice and hash-check the two copies against each other to ensure no corruption, which is waste of bandwidth on both sides.

      Thanks for following up with the additional feedback.

       

      By the way though, since Dropbox enforces TLS (i.e., it will redirect any http:// shared link URLs to https://), I believe you can technically rely on TLS to ensure integrity of the download against any corruption in transit. The TLS specification states:

      The primary goal of the TLS Protocol is to provide privacy and data integrity between two communicating applications.
      The connection is reliable. Message transport includes a message integrity check using a keyed MAC.
