Link header value is empty for products

I have a private app the makes calls to the products.json and paginates through the results using the now depreciated method. I am trying to use the new 2019-10 api version but when I make a call to {my store address}/admin/api/2019-10/products.json the link header value is empty.

…

HTTP_X_SHOPIFY_SHOP_API_CALL_LIMIT:1/80

X-Shopify-Shop-Api-Call-Limit:1/80

X-Shopify-API-Version:2019-10

Link:; rel=“next”

…

I have tried adding ?limit=250 and some other variations but the link header still returns empty.

@homiebe Yes indeed I was having the same issue, I was emailing myself the results of the headers to check their values before I began in earnest and it was blank. The brackets were causing my email client to try and render the value as html. Thanks for the link!

$curl = curl_init(); 
curl_setopt_array($curl, 
array( CURLOPT_URL => 'https://your-store.myshopify.com/admin/api/2023-07/products.json?fields=variants%2Cid&limit=2',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HEADER =>  1,
  CURLOPT_HTTPHEADER => array(
    'X-Shopify-Access-Token: your_token'  ),
));

$response = curl_exec($curl);

$header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);
$header = htmlspecialchars(substr($response, 0, $header_size));

var_dump($header);

die;
curl_close($curl);

Below 2 lines are game changers these will fix the issue

$header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);
$header = htmlspecialchars(substr($response, 0, $header_size));
