    I'm not sure I follow your message, but you should specify it in both places. The /oauth2/authorize page redirect_uri parameter specifies where to send the user after they authorize the app, and the 'redirectUri' you pass to 'getAccessTokenFromCode' is just a string sent up in a /oauth2/token API call to verify that it matches.

That's correct, that parameter isn't currently implemented in the Dropbox JavaScript SDK, but I'll be sure to pass this along as a feature request. You can add it to the /oauth2/authorize URL in your app's own code though, by modifying the URL returned by getAuthenticationUrl.

Greg-DB Would you be able to expand on how that exactly gets done? Thanks!

    For example, where authUrl is the URL you got from getAuthenticationUrl, you can modify it like this:

    var url = new URL(authUrl);
var urlParams = new URLSearchParams(url.search);
urlParams.set('force_reapprove', 'true');
url.search = urlParams;
console.log(url.href);
