How do I turn likes to variable with Firebase?

Hi, i need to turn the likes from a post on facebook to a variable in a game.

I think this is possible sending the data likes from facebook to a server like firebase and the server to the game.

I found this instruction from facebook:

developers.facebook.com/docs/graph-api/reference/v2.8/object/likes

But i dont know what to do with this codes.

Can you post the text that it replies with?

From the API page, it looks like it is a JSON object whose "total_count" field is the one you are interested in.

You should be able to use Yann 's JSON plugin or rexrainbow 's Hash plugin to parse the JSON and access the value you want.
