I want to build Facebook login to my Rhomobile app. Coding languages are html, JS, Ruby. Therefore can not use Android sdk or iOS sdk. JS sdk gives the error "Given URL is not allowed by the Application configuration". Reason for this is app running on local server with random port. eg.: http://127.0.0.1:24738/
I did it previously using redirection service rediectme.to. But this service is not running anymore.
Anyone has working example for this?
