I want to login to app with twitter, i follow this documentation but i got this error
[TwitterKit] did encounter error with message "Error obtaining user auth token.": Error Domain=TWTRLogInErrorDomain Code=-1 "Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings" UserInfo={NSLocalizedDescription=Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings} error: Optional("Request failed: forbidden (403)")
i found this answer in twitter developer documentation
If you do receive this error message, please check the URL that you are using with the callback_url parameter in your oauth/request_token call and make sure that this URL has been whitelisted in your app settings on apps.twitter.com.
but i don't understand that, i don't know what to do any help please ?
