my $fb = Net::Facebook::Oauth2->new( application_id => 'your_application_id', application_secret => 'your_application_secret', callback => 'http://yourdomain.com/facebook/callback' ); # get the authorization URL for your application my $url = $fb->get_authorization_url( scope => [ 'public_profile', 'email', 'offline_access', 'publish_stream' ], display => 'page' ); Now redirect the user to this C<$url>. Once the user authorizes your application, Facebook will send him/her back to your application, on the C link provided above. Inside that callback route, use the verifier code parameter that Facebook sends to get the access token: # param() below is a bogus function. Use whatever your web framework # provides (e.g. $c->req->param('code'), $cgi->param('code'), etc) my $code = param('code'); my $access_token = $fb->get_access_token(code => $code); If you got so far, your user is logged! Save this access token in your database or session. Later on you can use it to communicate with Facebook on behalf of this user: my $fb = Net::Facebook::Oauth2->new( access_token => $access_token ); my $info = $fb->get( 'https://graph.facebook.com/v2.2/me' # Facebook API URL ); print $info->as_json; =head1 DESCRIPTION Net::Facebook::Oauth2 gives you a way to simply access FaceBook Oauth 2.0 protocol For more information please see example folder shipped with this Module =head1 SEE ALSO For more information about Facebook Oauth 2.0 API Please Check L get/post Facebook Graph API L =head1 USAGE =head2 Cnew( %args )> Pass args as hash.

Once the user authorizes your application, Facebook will send him/her back to your application, on the C link provided above. Inside that callback route, use the verifier code parameter that Facebook sends to get the access token: # param() below is a bogus function. Use whatever your web framework # provides (e.g. $c->req->param('code'), $cgi->param('code'), etc) my $code = param('code'); my $access_token = $fb->get_access_token(code => $code); If you got so far, your user is logged! Save this access token in your database or session. Later on you can use it to communicate with Facebook on behalf of this user: my $fb = Net::Facebook::Oauth2->new( access_token => $access_token ); my $info = $fb->get( 'https://graph.facebook.com/v2.2/me' # Facebook API URL ); print $info->as_json; =head1 DESCRIPTION Net::Facebook::Oauth2 gives you a way to simply access FaceBook Oauth 2.0 protocol For more information please see example folder shipped with this Module =head1 SEE ALSO For more information about Facebook Oauth 2.0 API Please Check L get/post Facebook Graph API L =head1 USAGE =head2 Cnew( %args )> Pass args as hash.
