Hi, i am able to create a custom app, but unable to install it on development store and our Shopify account as well.


from development store my URL look like this(https://XXXXX/sku-shopify2/?hmac=8622fc2033172237bf7c1afd1c8598e2e23313b3262e9b3f10dd072c9bd12ffe&sh... )


I am attaching my install.php and generate.php(redirect url)

install.php

 

 

 

<?php
$shop = $_GET['shop'];

$api_key = "2f17b4c22649532380d95490cf17673e";
$scopes = "read_orders,write_orders,read_products,write_products";
$redirect_uri = "https://XXXXX/sku-shopify2/generate_token.php";

// Build install/approval URL to redirect to
$install_url = "https://" . $shop . ".myshopify.com/admin/oauth/authorize?client_id=" . $api_key . "&scope=" . $scopes . "&redirect_uri=" . urlencode($redirect_uri);

// Redirect
header("Location: " . $install_url);
die();

 

 

 

generate.php

 

 

 

<?php

// Get our helper functions
require_once("inc/functions.php");

$api_key = "2f17b4c22649532380d95490cf17673e";
$shared_secret = "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";

$params = $_GET; // Retrieve all request parameters
$hmac = $_GET['hmac']; // Retrieve HMAC request parameter

$params = array_diff_key($params, array('hmac' => '')); // Remove hmac from params
ksort($params); // Sort params lexographically

$computed_hmac = hash_hmac('sha256', http_build_query($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);
echo $access_token = $result['access_token'];

} else {
// Someone is trying to be shady!
die('This request is NOT from Shopify!');
}
