Direct file upload to Dropbox

Hi depotsy,

It depends on how large are those files. One option, for not very large files, is usage of Dropbox Saver; take a look here for example. Other option is implemented client side application (in addition to your server side application) working with upload session; largest possible file would be 350GB.

Hope this gives direction.

depotsy As Здравко said, you can implement uploads client-side.

And while you don't need to use an official SDK, we do recommend doing so if possible. For example, the official Dropbox JavaScript SDK supports running in client-side browser JavaScript.

There are a few options for uploading to the user's own Dropbox account:

• filesUpload for smaller files
• filesUploadSessionStart, etc. for larger files
• filesSaveUrl (or the Dropbox Saver) for smaller files hosted at URLs

Or if don't want to rely on them having a shared folder with you, you can use copy references to copy files between accounts:

• filesCopyReferenceGet on the file in the user's account, and then
• filesCopyReferenceSave in your account

Or if you don't want to rely on the user having their own Dropbox account at all, there is an option for client-side uploading to your own account without exposing your access token to the user:

• filesGetTemporaryUploadLink for smaller files; you would run this server-side in your account, then pass the link to the user's browser and upload to the link from there
