Hello!

i have been posting this issue over two week but no one can anser the questions.

i have an app it is public not private !

 

I use some variables for Admin side it works perfect!

url : /admin/api/2020-07/graphql.json

if (!is_null($token)) $request_headers[] = "X-Shopify-Access-Token: " . $token;
$request_headers[] = "Accept: application/json";
$request_headers[] = "Content-Type: application/json";
$request_headers[] = "Host: ".$shop;
$request_headers[] = "cache-control: no-cache";

--->OK

$token variable is access key for shopify user who installs the app and i get the key durring installation.

I know it is different options for public app to use graphql api so i use same token for  strofront!

url : /api/2020-07/graphql.json

if (!is_null($token)) $request_headers[] = "X-Shopify-Storefront-Access-Token: " . $token;
$request_headers[] = "Accept: application/json";
$request_headers[] = "Content-Type: application/json";
$request_headers[] = "Host: ".$shop;
$request_headers[] = "cache-control: no-cache";

 

----> NOT OK!

response return empty and response code is 403

i did not understand what shopfy means in the documantation about "X-Shopify-Storefront-Access-Token"

i do not see any spesific key for this method. by the way my app is not in sale channel.

one test store installed the app and i am using access key for that store in $token; variaable.

if you ask where do i generate $token; variable, here is the answer:

$api_key = "ad610a996a4aa4f3546890eexxxxxxxx";
$shared_secret ="shpss_511156b13933c45808857dedxxxxxxxx";
$params = $_GET; // Retrieve all request parameters
if(isset( $_GET['hmac']))
$hmac = $_GET['hmac']; // Retrieve HMAC request parameter
 
if(isset($_GET["shop"]));
 $shop=$_GET["shop"];
$params = array_diff_key($params, array('hmac' => '')); // Remove hmac from params
ksort($params); // Sort params lexographically
 
if(isset($params["url"]))
unset($params["url"]);
$computed_hmac = hash_hmac('sha256', http_build_query($params), $shared_secret);
 
// Use hmac data to check that the response is from Shopify or not
if (hash_equals($hmac, $computed_hmac)) {
 
// Set variables for our request
$query = array(
"client_id" => $api_key, // Your API key
"client_secret" => $shared_secret, // Your app credentials (secret key)
"code" => $params['code'] // Grab the access key from the URL
);
 
// Generate access token URL
$access_token_url = "https://" . $params['shop'] . "/admin/oauth/access_token";
 
// Configure curl client and execute request
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $access_token_url);
curl_setopt($ch, CURLOPT_POST, count($query));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($query));
$result = curl_exec($ch);
curl_close($ch);
 
// Store the access token
$result = json_decode($result, true);
$access_token = $result['access_token'];

//$access_token is equals $token variable.

however, i cannot access data with graphql api for storefront api

please help me to solve this problem..

Thank you!

Hey @Aljazari 

You might want to check out this documentation on getting the storefront access token: https://shopify.dev/docs/storefront-api/getting-started, specifically the part for public apps.
