I can not find a place where I would paste the API, because there is no place where it would be used at all. Can you point me in the code where you have to add it?
{jamap locations='{"location":{"0":"Agencja"},"latitude":{"0":"53.023289"},"longitude":{"0":"18.601054"},"info":{"0":""}}' disable_scrollwheelzoom='0' }{/jamap}
