Please correct the below for creating custom SOAP API.

VendorModuleetcdi.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <preference for="VendorModuleApiDataQueueInterface" type="VendorModuleModelQueue" />
</config>

VendorModuleetcwebapi.xml

<?xml version="1.0"?>
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">
<route url="/V1/sync/getProduct/:limit" method="GET"> 
 <service class="VendorModuleApiQueueRepositoryInterface" method="getProductUpdate"/> 
 <resources>
 <resource ref="anonymous" />
 </resources>
</route>

VendorModuleApiQueueRepositoryInterface.php

namespace VendorModuleApi;

/**
 * VendorModule CRUD interface.
 * @api
*/
interface QueueRepositoryInterface

 public function getProductUpdate($limit); 

Here is my doubt

Is my Data file correcT?

VendorModuleApiDataQueueInterface.php

<?php

namespace MagentoSalesApi;


interface OrderRepositoryInterface

 public function getList(MagentoFrameworkApiSearchCriteria $searchCriteria);

 public function get($id);

 public function delete(MagentoSalesApiDataOrderInterface $entity);

 public function save(MagentoSalesApiDataOrderInterface $entity);

VendorModuleModelQueue.php

namespace VendorModuleModel;

use MagentoFrameworkModelAbstractModel;
use MagentoFrameworkDataObjectIdentityInterface;
use VendorModuleApiDataQueueInterface;

 class Queue extends AbstractModel implements QueueInterface,IdentityInterface
 
 public function getProductUpdate($limit)
 
 //echo 'getproductudate';die;
 if(!isset($limit)) 
 
 return json_encode(array("result"=>false,"message" => 'Argument is missing'));
 

 if(!$this->_status)
 
 return json_encode(array("result"=>false,"message" => 'VendorModule Plugin is disabled'));;
 

 if($this->_bulkImport == "enable")
 
 return json_encode(array("result"=>false,"message" => 'Bulk Product Import in progress, Please try again later'));; 
 

 $data = $this->_helper->getProductUpdate($limit);
 if(isset($data))
 
 return json_encode(array("result" => true,"data" => $data));
 

 return json_encode(array("result" => false,"message" => "Record not found"));

In my URL i tried:

http://localhost:1338/magento2x_3/soap/default?wsdl&services=moduleQueueRepositoryV1

I get

exception 'Exception' with message 'Report ID: webapi-57a85520a7648; Message: Requested service is not available: "syncQueueRepositoryV1"'

First you must find your API from list APIs:

http://magento_host/soap/default?wsdl_list=1 

See all Soap APIs in doc:

http://devdocs.magento.com/guides/v2.1/soap/bk-soap.html.

After use program for creating SOAP requests like SoapUI OpenSource
