we are working on Magento Marketplace Multi vendor site.
Means Sellers can able to sell the products through our site.
Our sellers are selling the same products in other e-commerce site [not magento - http://www.flipkart.com/ ],
http://builtwith.com/flipkart.com - platform of flipkart site.
sellers using same sku in both our site and in flipkart.
what we want to achieve is display "same Quantity" in both sites.
Suppose if one product sold in flipkart, than quantity will decrease in flipkart.
same quantity should reflect in our site too for that sku.
flipkart provides an API for this : https://seller.flipkart.com/api-docs/FMSAPI.html
Is it possible to display same quantity in both sites using an API.
