Xamarin.Essentials.WebAuthenticator and Dropbox

Question

I don't seem to be able to find the correct combination of settings to use WebAuthenticator to login to Dropbox (API). Has anyone been able to get this to work? If so, how is the value set for the redirect uri in the Dropbox app configuration and what value is specified for the redirect uri in the AuthorizeAsync() call?

Hello,​

Welcome to our Microsoft Q&A platform!

The WebAuthenticator API consists mainly of a single method AuthenticateAsync which takes two parameters: the authorization Url and the call back Url. To authenicate the Dropbox in your application, you need to register your application in the Dropbox platform first. And you could get the Redirect URI there.

   var authResult = await WebAuthenticator.AuthenticateAsync(  
           new Uri(Authorization URL ),  
           new Uri(Redirect URI);  
     
   var accessToken = authResult?.AccessToken;  

For the details, you could google with the keyword as Easy Steps to Access Files in Dropbox and Use Them in a Xamarin App and Easy Xamarin Essentials with Web Authenticator to check the related documentation.
