API V2 temporary upload link max file size

[Hen4]

Hi all,

I'm creating an "anonymous" upload functionality (where the user-facing page does not have access to my dropbox tokens) and use the /get_temporary_upload_link method for this.

This generally works great, except that when the uploaded file exceeds exactly 314572800 bytes (300MB) the server throws an 409 Conflict error.

< HTTP/1.1 409 Conflict

This limitation is 100% repeatable and was mentioned before some years ago, see 

https://www.dropboxforum.com/t5/Dropbox-API-Support-Feedback/Large-uploads-via-get-temporary-upload-link-are-terminated-with/td-p/333377

The official documentation does not mention this limitation. I have a paid account and can have 100GB uploads per plan. How can I upload larger files? Presumably this works via the file requests mechanism, does this use some unofficial api  or mechanism?

Addendum: using a "file request" does allow anonymous users to upload larger files using that dropbox.com landing page, so clearly there is some kind of undocumented API that would enable this.

The information in the other thread you linked to is still accurate. Dropbox does not offer a way to programmatically upload larger files by link, but I'll add this thread to the feature request.
