PayPal Express Checkout JSとの統合：プロダクションID

Question

私はちょうど私たちのCMSにPayPal Express Checkout Integrationを実装しました。 Sandbox-IDではすべて正常に動作しますが、実際の環境では、お客様のPaypal API認証情報をGoogleのシステムに組み込む必要があります。 Paypalの開発者ドキュメントでは、これらの顧客資格情報をエクスプレスチェックアウト統合コードにどのように統合できるか、解決策は見つかりません。

誰か助けてくれますか？

    <div id='paypal-button'></div>       
         <script> 
          paypal.Button.render({ 

           env: 'production', // Specify 'sandbox' for the test environment, 'production' 

          style: { 
             size: 'medium', 
             color: 'silver', 
             shape: 'rect' 
            },         

          client: { 
            sandbox: 'ASoNxxxxxxxxxxxxxxxxxxx', 
            production: '$customer_api' 
           }, 

           payment: function(resolve, reject) { 
            // Set up the payment here, when the buyer clicks on the button 
            var env = this.props.env; 
            var client = this.props.client; 

            return paypal.rest.payment.create(env, client, {

              }, 
             ],
