How to get the generated url when accessing the instagram photo link using /media/? size=l at the end

Question

I’m trying to get the url that is displayed (switched) when accessing a link as for example on instagram https://www.instagram.com/p/B9MjyquAfkE/media/? size=l, the link generated after the click, comes from the instagram api, and as this same link generated has expiration time, there is no way to use it for long. Is there any way via php, to catch it without showing the page itself from the link? I tried to use Curl but could not get the result.

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, '"'.$dadosItemInstagram['imagem'].'"');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$ret = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

The $dadosItemInstagram['image'] array contains the link. I’ve been reading a lot before coming here, and so I understood instagram from an account authorization to access their api, for example to display images or videos on websites, except that the link has a certain duration so I’m stuck in this part, the solution I found was to add the /media/?size=l , at the end of the link, so I know if it’s the best too.

What happens is that this link is redirected to another url, so you need CURL to accept redirects. You can do this by setting the option CURLOPT_FOLLOWLOCATION:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
