Have no idea how the "update mode" works (how it works with "rev" param?).

Thanks for your help!

Could you show me the document of this API?

But not this one: https://www.dropbox.com/developers/documentation/http#documentation-files-upload_session-finish 

[David W.152]

Well, so this works:

"mode": {".tag": "update", "update": "xxxx"}

Hi David, apologies that the documentation and explorer aren't clear on how to use that. I'll send that along as feedback to get that fixed up. I'm glad to see you sorted this out already though.

You'll need a little bit more luck to work smoothly with API v2.
