Twitter Call back URL

I am working with twitter SDK to integrate with in ios app.When i follow all the step and create the customer key and put it in my app.When I run the app it show
"[TwitterKit] did encounter error with message

> "Error obtaining user auth token.": Error Domain=TWTRLogInErrorDomain
> Code=-1 "<?xml version="1.0" encoding="UTF-8"?><errors><error
> code="415">Callback URL not approved for this client application.
> Approved callback URLs can be adjusted in your application

> version="1.0" encoding="UTF-8"?><errors><error code="415">Callback URL
> not approved for this client application. Approved callback URLs can
> be adjusted in your application settings</error></errors>"

How to resolve this?

I just added on callback url field `twitterkit-<api/consumer Key>://`.
If you have an apiKey like `abc` you should add `twitterkit-abc://`. This work for iOS, for Android just add `twittersdk://`.

Finally I found the solution for my case. Hope it'll help someone else

Put this in URL Callback field.

**twittersdk://**

Hey everyone here is a simple fix that worked for me.

Go to:

Go into the settings tab.
Under Terms of Service URL uncheck the box that says:
"Unable Callback Locking"
Now test your app.

I had the same problem and the TwitterKit documentation is not accurate or Twitter has changed their policies. In any case, on the Twitter Apps site, the callback URL has to be set very specifically. The callback URL should be in the format:

twitterkit-{consumer/api key}://

For example:

twitterkit-128238aKjqlp123AKdasdf://

Also, this needs to be registered in your Info.plist exactly the same:

<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>twitterkit-128238aKjqlp123AKdasdf</string>
</array>
</dict>

More documentation is listed here:

Go to

Then in the "Settings" tab of your app.
Fill the "Callback URLs" form.

According to this documentation i guess you just have to enter a valid URL :

> NOTE: Although the callback URL will not be requested by Twitter Kit in your app, it must be set to a valid URL for the app to work with the SDK.
