Callback URL (redirect_uri) A URL associated with your client application. In some contexts, this must be a real URL that the client’s Web browser is redirected to. In others, the URL isn’t used; however, between your client application and the server (the connected appdefinition) the value must be the same. For example, you may want to use a value that identifies the application, such as http://mycomponent.myapp.
