Dropbox Community ModeratorHi 오부경,
I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:
- the name and version number of the platform and SDK/library you are using, if any
- relevant code snippet(s), but don't include any access or refresh token(s)
- the full text of any error or unexpected output
- 5-10 different 'X-Dropbox-Request-Id' response header values encountering the issue
I am using REAT API method using Rebex HTTP product without SDK.
Below is part of packet capture using Fiddler.
Please refer to it.

Hi 오부경
Thanks again for your patience while we looked into the issue you reported. Here's what we found:
- Regarding the "is_downloadable" field returned by the /2/files/list_revisions endpoint:
This field indicates whether the file can be downloaded directly (i.e., via /2/files/download), or if it needs to be exported (via /2/files/export) due to its file type. While the field name might suggest something about the availability of the file data, it’s actually not related to whether the file is still accessible. - Looking at the revision metadata you provided, we see that the server_modified timestamp for the file revision in question is "2024-01-07T01:43:42Z". As you noted, that’s over a year ago, and given that you're on a Basic account, that revision is likely no longer available based on your account’s version history retention limits. Feel free to review this article for more details: https://help.dropbox.com/delete-restore/version-history-overview#How-much-version-history-can-I-access.
That said, I'll pass this along as a feature request (specifically, the ability to distinguish between deleted file revisions that are still recoverable and those that are no longer available). I can't promise if or when that might be implemented though.
