How to get Inventory for merchant fulfilled product using amazon mws api?

Question

I am using MWS api for fetching inventory using ListInventorySupplyAsyncSample call but it gives inventory only for amazon fulfilled product. How to get inventory for product fulfilled by merchant?

Answer 1

The ListInventorySupply call is part of the Fulfillment Inventory API which deals exclusively with FBA (Fulfillment by Amazon) stock located in one of the Amazon warehouses.

Your own (merchant fulfilled) stock in your own (non-Amazon) warehouse is probably managed best outside Amazon, but should be available to "download" form Amazon by using the RequestReport call with a ReportType of _GET_MERCHANT_LISTINGS_ALL_DATA_. I haven't tried this myself, though.

You may see through my code use meertism's package from GitHub

`<?php
 $amazonSellerId         = 
 $amazonMWSAuthToken     = 
 $amazonAWSAccessKeyId   = 
 $amazonSecretKey        = 
 $amazonMarketPlaceId    = 
 $client = new MCS\MWSClient([
 'Marketplace_Id' => $amazonMarketPlaceId,
 'Seller_Id' => $amazonSellerId,
 'Access_Key_ID' => $amazonAWSAccessKeyId,
 'Secret_Access_Key' => $amazonSecretKey,
 'MWSAuthToken' => $amazonMWSAuthToken // Optional. Only use this key if you are a 
  third party user/developer
  ]);
  $reportId = $client->RequestReport('_GET_MERCHANT_LISTINGS_DATA_');
  sleep(20); 
  $report_content = $client->GetReport($reportId);
  foreach($report_content as $i)
  {
       if($i['seller-sku'] == sku)
         { $qty=$i['quantity'];
          }
  }
  echo $qty;`

I am currently using the Amzpecty API service to get real-time inventory of Amazon sellers given the ASIN.
