Facebook API - Secure Canvas URL

Question

I’m trying to make an app work on Facebook and have interaction with the site I’m developing. The goal is for the user to log in through Facebook on the site.

It turns out that every time I try to add the site in the Facebook API settings, 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.

See that in the picture has the field App Domains. 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 set this up on the server ?

And in the field Secure Page Tab URL have to put that websiteseguro.com to work. The question is can you cheat Facebook and leave so. But be like this the application does not work on Facebook, but works on the site.

Anyway, Facebook even for this is very boring to use.

I managed to resolve that issue.

Facebook in this field accepts only the protocol HTTPS.

That is, if we want to put some page of the site in a TAB (Tab) on Facebook we need to hire the hosting SSL service, which makes the domain also be accessed by the protocol HTTPS.
