Need a custom web-page where students upload files into a teacher's Dropbox. I use Dropbox for Business and created a web-page with upload files from my web-page to my dropbox folder with API/C#/OAuth2, what about other people uploading into my folder?

Here is what I have:

var result = OAuthUtility.Put
(
"https://api-content.dropbox.com/1/files_put/auto/",

new HttpParameterCollection
{
{ "access_token", token },
{ "overwrite", "true" },
{ "path", serverPath },
{ FileUpload1.PostedFile }
}
);

Here is what I am looking to do.
var result = OAuthUtility.Put
(
" What link do I have here in order for other users to place into my folder, example this one? ",
https://www.dropbox.com/sh/noxsnids7gtm5dl/AABQm62hVLh_iSW1fhfTgqFLa?dl=0
new HttpParameterCollection
{
{ "access_token", token },
{ "overwrite", "true" },
{ "path", serverPath },
{ FileUpload1.PostedFile }
}
);
