Access public folder with Dropbox API using C#

Hi,

I am working on a project that will access files in a publicly shared folder the url of which looks like this:-

https://wixlabs---dropbox-folder.appspot.com/index?instance=UexTyTTXTALjKbz1f1P3H5nZAFTiMsLw2wWcu_0uebU.eyJpbnN0YW5jZUlkIjoiNzk4YzZlYTUtMDg5Yi00ZjFlLWI2NzMtOWYxZjA1OTU1YmQ5IiwiYXBwRGVmSWQiOiIxNDkyNDg2NC01NmQ1LWI5NGItMDYwZi1jZDU3YmQxNmNjMjYiLCJtZXRhU2l0ZUlkIjoiYmRkMzFlNjMtY2I5Ny00ZTMxLWI5NGEtMGFhNmI5MzgwYjY3Iiwic2lnbkRhdGUiOiIyMDE4LTEwLTA0VDAwOjE4OjIyLjM5MFoiLCJ1aWQiOm51bGwsInZlbmRvclByb2R1Y3RJZCI6bnVsbCwiZGVtb01vZGUiOmZhbHNlfQ&target=_top&width=576&compId=comp-jmtmo1bb&viewMode=viewer-seo

When I use the api I get:- ApiException`1: shared_link_not_found/.

This is the code I am using:-

Snippet

private async static Task RunOnPublicUrlAsync(string url)
		{
			using (var dbx = new DropboxClient("Access Code here"))
			{
				var metadata = await dbx.Sharing.GetSharedLinkMetadataAsync(url);
				Console.WriteLine($"{metadata.IsFolder}, {metadata.Name}");
			}
		}

Any help or advice will be greatly appreciated. Thanks in advance.
