Hi @vishalsanwar86 

You can write a script that will fatch product's inventory data from pos and update the product inventory in magento.
POS module provides product collection so you will be able to get data.

Here is working code for update qty from Rest API

<?php
$adminUrl = 'http://localhost/magento2/rest/V1/integration/admin/token/';
$ch = curl_init();
$data = array("username" => "admin", "password" => "admin"); //Admin Login details

$data_string = json_encode($data);
$ch = curl_init($adminUrl);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$token = curl_exec($ch);
$token= json_decode($token);
$headers = array("Authorization: Bearer $token","Content-Type: application/json");
$skus = array(
'100001' => 66,
'100002' => 99
);
//Here 100001 and 100002 are SKU and 66 and 99 are Qty

foreach ($skus as $sku => $stock) {
$requestUrl='http://localhost/magento2/rest/V1/products/' . $sku . '/stockItems/1';
$sampleProductData = array(
"qty" => $stock
);
$productData = json_encode(array('stockItem' => $sampleProductData));

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $requestUrl);
curl_setopt($ch,CURLOPT_POSTFIELDS, $productData);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

unset($productData);
unset($sampleProductData);
}
