Shopify收据和退款按钮显示为灰色

我正在将shopify整合到我管理的网站之一，一个运输网站 . 我正在使用API来创建包含数据库中项目的订单 . \

发出订单时，将根据从我们网站选择的网关（现金，支票或信用卡）进行交易 . 此交易的订单发送到我们的商店，可以在POS应用程序上看到 .

问题是我无法访问POS应用程序中的退款或收据按钮 . 我可以使用shopify后端退款，但不能在POS上退款 . 这是令人烦恼的，是我能够在我们的网站上实现此功能之前唯一的事情 .

以下是发送的订单代码

$order =
        array(
        'fulfillment_status' => 'fulfilled',
        'send_receipt' => 'true',
        'send_fulfillment_receipt' => 'true',
        );

    // Second part of order with items and customer

    if($ShippingQuantity !== 0.00){
      $order2 = array('line_items' => array(
            array('title' => 'Shipping',
            'price' => '10',
            'quantity' => $ShippingQuantity,
          )
        )
      );
    }

    if($HandlingQuantity !== 0.00){
      $order3 =array('title' => 'Handling',
            'price' => '5',
            'quantity' => $HandlingQuantity,
          );

    $order2['line_items'][] = $order3;
    }

    if($DutyQuantity !== 0.00){
          $order4 =array('title' => 'Duty',
                'price' => '0.01',
                'quantity' => $DutyQuantity,
              );
    $order2['line_items'][] = $order4;
    }

    if($ConsolidationQuantity !== 0.00){
          $order5 =array('title' => 'Consolidation',
                'price' => '10',
                'quantity' => $ConsolidationQuantity,
              );
    $order2['line_items'][] = $order5;
    }

    if($DeliveryQuantity !== 0.00){
          $order6 =array('title' => 'Delivery',
                'price' => '20',
                'quantity' => $DeliveryQuantity,
              );
    $order2['line_items'][] = $order6;
    }

    $customerandtrans = array('customer' => array(
      'id' => $currentcustID,
    ),'note' =>'purchase made at '.$pickup.'',
                'transactions' => array(
                array('amount' => $Total,
                      'gateway' => $gateway,
                    )
            )
    );


    $final = array_merge($order,$order2,$customerandtrans);
    $finaljson = json_encode($final);
    }
        }


        $ch = curl_init($baseUrl.'orders.json'); //set the url
        $data_string = json_encode(array('order'=>$final)); //encode the product as json
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  //specify this as a POST
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); //set the POST string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //specify return value as string
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($data_string))
        ); //specify that this is a JSON call
        $server_output = curl_exec ($ch); //get server output if you wish to error handle / debug
        curl_close ($ch); //close the connection

        //var_dump($data_string);
        //var_dump($server_output);

        $decoded = json_decode($server_output,true);
        //var_dump($decoded);
        $reg_id = $decoded['order']['id'];
        $amount = $decoded['order']['total_price'];
        if($reg_id){
        echo "An order has been created with ID $reg_id ";

这是交易代码

$order_target2="orders/".$reg_id."/transactions.json";

    $trans =
    array('kind' => 'sale', 'receipt' => array( 'testcase' => 'true', 'authorization' => '123456',),);

    $ch = curl_init($baseUrl.$order_target2); //set the url
    $data_string = json_encode(array('transaction'=>$trans)); //encode the product as json
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  //specify this as a POST
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); //set the POST string
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //specify return value as string
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string))
    ); //specify that this is a JSON call
    $server_output = curl_exec ($ch); //get server output if you wish to error handle / debug
    curl_close ($ch); //close the connection


    //var_dump($data_string);
    //var_dump($server_output);

    $decoded = json_decode($server_output,true);
    //var_dump($decoded);
    $order_id = $decoded['transaction']['order_id'];
    if($order_id){
      echo "Transaction successfully made at order $order_id ";
    }
