Graph API Access without HTTPS

Question

We have a Facebook app running on our production having HTTPS and it works fine. For same app we have a development/stage setup but don’t have HTTPS. Till 2012-02-23, both the server works fine. Now our app on development/stage server throws below error:

1. CurlException: 28: connect() timed out!

2. Warning: file_get_contents(https://graph.facebook.com/me?access_token=...): failed to open stream: Connection timed out

I have question:

1. Is it mandatory to have a HTTPS to communicate with Graph API?

2. Or, Facebook does blacklisting of IP – if so how to make IP white list?

Thanks in advance...

Answer 1

1. Yes, if passing an access token ( which is needed for most API calls) you must use HTTPS
2. Possibly, but it's far more likely to be a firewall problem on your side - Facebook would accept the connection but return an error message, but you're not even getting a connection to Facebook
