I have created a new module which accepts child product id as parameter and returns the parent product id and other attributes like name , thumbnail....
registeration.php
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'WebAPI_GetParentProductThumbnail',
__DIR__
);
etc/module.xml
<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="WebAPI_GetParentProductThumbnail" setup_version="1.0.0"/>
</config>

Api/ChildThumbnailManagementInterface.php
<?php
namespace WebAPI\GetParentProductThumbnail\Api;
interface ChildThumbnailManagementInterface
{
/**

public function getChildThumbnail($product_id);
}
Model/ChildThumbnailManagement.php
<?php
namespace WebAPI\GetParentProductThumbnail\Model;
class ChildThumbnailManagement
{

public function getChildThumbnail($product_id)
{
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
if($product_id != ""){
//This method getParentIdsByChild($child_id) get the parent id of a configurable product.
$parent_product = $objectManager->create('Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable')->getParentIdsByChild($product_id);
if(isset($parent_product[0]))
{
$parent_id = $parent_product[0];
//Parent object where you can get Thumbnail, name.... etc
//$parent_object = $objectManager->create('Magento\Catalog\Model\Product')->load($parent_product[0]);
echo parent_id;
}
}
return null;
}
