I'm trying to make an app work on Facebook and interact with the site I'm developing. The goal is for the user to sign in via Facebook on the site.
It happens that every time I try to add the site in the API settings of Facebook, it accuses this error:
This must be derived from Secure Canvas URL, Mobile Site URL, Unity Binary URL, Site URL ou Secure Page Tab URL.
Notice that the image has the App Domains field. It is this field that does not enter at all. Is it mandatory to be HTTPS? I do not understand.
If yes, how do I configure this on the server?
And in the Secure Page Tab URL field you have to do this websiteseguro.com to work. The question is can fool Facebook and leave like that. But to be so the application does not work on Facebook, but it works on the site.
Anyway, Facebook even for this is very annoying to use.
Be Crazy Cachorrera!
