メタフェイズではShopifyを利用したストア構築を行っています。
今回はWebhookを処理する方法を紹介いたします。

1 Webhookを作成しURLを設定する

2 設定したURLへ下記を記述したindex.phpを配置する

<?php
define('SHOPIFY_APP_SECRET', 'xxx');
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);
}

$hmac_header = $_SERVER['HTTP_X_SHOPIFY_HMAC_SHA256'];
$data = file_get_contents('php://input');
$verified = verify_webhook($data, $hmac_header);
$headers = getallheaders();
$txt = [
"----------------verified---------------",
$verified ? "true":"false",
"----------------header---------------"
];
foreach ($headers as $key => $value){
    $txt[] = "{$key} : {$value}";
}
$txt[] = "----------------body---------------";
$txt[] = $data;
if( $file_handle = fopen( "./webhook".date("YmdHis").".txt", "w") ) {
    fwrite( $file_handle, implode("\n",$txt));
    fclose( $file_handle);
}
http_response_code(200);

define('SHOPIFY_APP_SECRET', 'xxx');の「xxx」の部分は下図の赤枠内の文字列で置き換えて下さい。

3 確認する

shopify上で買い物を完了すると、設定したURLの配下にWebhookで受け取った情報がテキストファイルで保存されています。
