Updated redirect_uri not working

Hello,

When I first created a dropbox app, my redirect_uri was http://localhost:4200/. Everthing was working fine and I continued to develop the application, then I needed to updated the redirect_uri, I changed it to http://localhost:4200/third-party-redirect/ and https://3e0cecfb.ngrok.io/third-party-redirect. After updating, I am not able to authenticate my users anymore. I am getting this error

Invalid redirect_uri. It must exactly match one of the redirect URIs you've pre-configured for your app (including the path).

If I revert back to the old redirect_uri, http://localhost:4200/ then everything is working fine. How can I update the redirect_uri ?

As a security feature, all redirect URIs used for an app must be pre-registered for the app. If you attempt to use a redirect URI that hasn't been registered, you'll receive this error.

To register an OAuth 2 redirect URI, access the app's page on the App Console by clicking on the app's name there:

https://www.dropbox.com/developers/apps

Then, add the desired redirect URI (exactly as it will be used) to the "OAuth 2: Redirect URIs" section.

I have the same problem

What was your solution for this ?

@evry1falls The error originally mentioned here occurs when your app attempts to use a redirect URI that you haven't pre-registered for it, so double check that you've registered the exact redirect URI that you're using. You can find more information on how to do so in my earlier comment.

Hi,

In case of the same error Google let the developer the expected URI. So it is easy to add it in the list. Is there a way to have a similar information with DropBox?

@Marc_Gandar I'm not sure I understand your message. Can you clarify?

Do you mean you'd like Dropbox to show the unregistered redirect URI that was attempted to be used in the invalid redirect URI error itself? Dropbox does currently do that on that error page, where the text would look like this:

Error (400)
It seems the app you were using submitted a bad request. If you would like to report this error to the app's developer, include the information below.
