Callback URL help

[MeKyleH]

I'm testing this out with Twitter. When I use the _loginWithAuth0() method I get navigated correctly to the Auth0 with the Twitter option and the email/password option. However, when I select Twitter I get an error in my simulator stating:

Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings.

and the logs show:

Object {
  "errorCode": undefined,
  "params": Object {
    "error": "access_denied",
    "error_description": "Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings",
    "exp://localhost:19000/--/expo-auth-session": "",
  },
  "type": "success",
  "url": "exp://localhost:19000/--/expo-auth-session#error=access_denied&error_description=Callback%20URL%20not%20approved%20for%20this%20client%20application.%20Approved%20callback%20URLs%20can%20be%20adjusted%20in%20your%20application%20settings",
}

However, if I use the _loginWithAuth0Twitter() method I simply get the same error above, nothing opens in the webview. I've tried setting up my Auth0 application callback URLS as such:

https://auth.expo.io/@USERNAME/SLUG,
https://auth.expo.io/@USERNAME/SLUG/callback,
expo://APPLICATION.auth0.com/ios/SLUG/callback,
exp://localhost:19000/--/expo-auth-session,
exp://localhost:19000/--/expo-auth-session/callback

and my Twitter App callback URLs are set as:

https://auth.expo.io/@USERNAME/SLUG,
https://APPLICATION.auth0.com

Can someone take a look at their callback URLs and give me a suggestion please. Thanks!

I figured out the issue. In the Twitter Developer console for the callback Url I was using:

https://PROJECTID.auth0.com/callback

and it should have been:

https://PROJECTID.auth0.com/login/callback

As the second callback Url I have added:

exp://

And it works like a charm. Hopefully, this helps someone in the future.
