Вывожу на сайте так
function getInstagramFeed(username, container, items) {
if(!$(container).length)
return false;
items = items || 32;
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if(xmlhttp.readyState==4 && xmlhttp.status==200) {
data = xmlhttp.responseText;
data = data.split("window._sharedData = ");
data = data[1].split("<\/script>");
data = data[0];
data = data.substr(0, data.length-1);
data = JSON.parse(data);
data = data.entry_data.ProfilePage[0].graphql.user;
if(data.is_private) {
console.log('This account is private');
return false;
}
else {
var imgs = data.edge_owner_to_timeline_media.edges;
max = (imgs.length>items) ? items : imgs.length;
if(!max)
return false;
var html = "<div class='ig-wrapper'><div class='ig-container'>";
for(var i=0; i<max; i++) {
var url = "https://www.instagram.com/p/"+ imgs[i].node.shortcode +"/";
var type = "";
if(imgs[i].node.__typename=="GraphVideo")
type = " class='video'";
else if(imgs[i].node.__typename=="GraphSidecar")

var caption = imgs[i].node.edge_media_to_caption.edges[0].node.text;
caption = caption.replace(/#/g," #");
