App reviews, troubleshooting, and recommendations
Hello, shopify app developer. I am developing an app while I have been facing a problem at almost last steps of developments.
I have succesfully registered an webhooks, we can see status after installed app. check below...
But after uninstalled app it should triggred and removing data from database which I request on delete.php file and also should create .log file to store response data. But nothing is happen. I think there might be a problem with delete.php file. I uploaded full delete.php file for your kind information. please help me if you can.
<?php
require_once("inc/db_connect.php");
require_once("inc/functions.php");
define('SHOPIFY_APP_SECRET', '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'); // Replace with your SECRET KEY
function verify_webhook ($data, $hmac_header){
$calculated_hmac = base64_encode(hash_hmac('sha256', $data, SHOPIFY_APP_SECRET, true));
return hash_equals($hmac_header, $calculated_hmac);
}
$res = '';
$hmac_header = $_SERVER['HTTP_X_SHOPIFY_HMAC_SHA256'];
$topic_header = $_SERVER['HTTP_X_SHOPIFY_TOPIC'];
$shop_header = $_SERVER['HTTP_X_SHOPIFY_SHOP_DOMAIN'];
$data = file_get_contents('php://input');
$decoded_data = json_decode($data, true);
$verified = verify_webhook($data, $hmac_header);
if( $verified == true ) {
if( $topic_header == 'app/uninstalled' || $topic_header == 'shop/update') {
if( $topic_header == 'app/uninstalled' ) {
$sql = "DELETE FROM `AccessToken` WHERE store_url='" . $shop_header . "' LIMIT 1";
$result = mysqli_query($conn, $sql);
$response->shop_domain = $decoded_data['shop_domain'];
$res = $decoded_data['shop_domain'] . ' is successfully deleted from the database';
} else {
$res = $data;
}
}
} else {
$res = 'The request is not from Shopify';
}
error_log('Response: '. $res); //check error.log to see the result
