Pass data from yaml to php

hi everyone, I have a yaml file which returns an API. like this in example:

MYAPI: "https://prova1api.herokuapp.com/RedHotCHiliPeppersDiscography"

I would like to take MYAPI and pass it in a php file, like this in example:

$ api_data = json_decode ($ MYAPI, true);
$ this-> grav ['twig'] -> twig_vars ['api_data'] = $ api_data;
