API Error Code 191: Invalid Argument on using Facebook Login

Asked By 50 points N/A Posted on -

I have this app which I am making and I have FaceBook login included in it. When I try logging using this, invalid argument shows up, and when I tried configuring it, the next one API Error Code 191 shows. How do I fix this? Can anyone give me the right way of integrating FaceBook login in any applications?

FaceBook Login

API Error Description: The specified URL is not owned by the application

Error Message: redirect_url is not owned by the application.

Hello Joby,

You may be getting that error because of incorrect settings. You will therefore need to go to https://developers.FaceBook.com/ and then edit the application that you are working on. Go to the "website" tab and then look for "Site URL". It should be set to your website's URL "http://yoursite.com/". In case you are using subdomains, you will need to update "Site Domain" to be "yoursite.com"
