Facebook : Given URL is not allowed by the Application configuration

Question

What is wrong here? If a user clicks on the login button he is redirected to http://www.facebook.com/plugins/login.php?action=like&api_key=211295588901671&channel=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%3Fversion%3D3%23cb%3Df207fe8ecd56db2%26origin%3Dhttp%253A%252F%252F188.24.5.134%252Ff3dedfc22a9c9ac%26relation%3Dparent.parent%26transport%3Dflash&locale=en_US&login_text=&max_rows=1&sdk=joey&show_faces=true&width=200 which gets me to the facebook error Given URL is not allowed by the Application configuration.

Answer 1

I believe it's because the URL the request is made from is not under your Site URL.

Look at your "origin" parameter in the URL you've submitted.

You can only make calls from the location you've defined as your Site URL.

Answer 2

I have used login url in following format

https://www.facebook.com/dialog/oauth? client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=email,read_stream

as per documented in http://developers.facebook.com/docs/authentication/ and it works. I get back request on my web page url provided in application config as mentioned. http://YOUR_URL?code=A_CODE_GENERATED_BY_SERVER
