Dropbox StaffAshu7878 Right now, the direct links returned by the Dropbox Chooser are always on dl.dropboxusercontent.com, but that isn't officially documented or guaranteed, so I can't promise that won't change.
I'll pass this along as a request to officially document/guarantee that, but I can't say if or when that might be done.
Hi Greg,
The direct link domain is going to be same (which is dl.dropboxusercontent.com) for all the countries from where user accesses dropbox account or it will change? What I mean is if user accesses it from uk will it change to something like this - dl.dropboxusercontent.co.uk ? We have user's across globe who will be accessing this.
Also the problem I am trying to solve here is not about the domain name but more of how to verify that source of direct link is from DropBox in the request. If a malicious user intercepts the request and modifies the direct link in the request, a different file will be uploaded.
I would love to know how some of other people here who use DropBox chooser have solved this kind of problem.

Ashu7878 The domain is the same for all users from all countries. I just can't promise that it won't change in the future.
In general though, there isn't a way to verify the source of the link since it is shared locally in JavaScript in the client, and the client can't be trusted (since it is under the control of the user, who may or may not be malicious). If you have any general web security questions, I recommend reaching out to a security professional.
