Walmart MCS Fulfillment

it doesn't work it does not push updates from Walmart to shopify. some of the order did not get fulfilment update in weeks. Contacted support and they told me they can not do anything about it.

Integrating the Walmart MCS connection was smooth and effortless from day one. It allowed us to reliably scale our shipping infrastructure and get orders into our customers' hands faster and more dependably. If you're looking to streamline multi-channel fulfillment, I can't recommend Walmart MCS enough.

This connection to our WFS inventory was exactly what our business needed to scale. We use to have to manually submit every order from our own website to our MCS and manually sync back tracking numbers to our Shopify and Walmart MCS app solves it all. It was seamless to setup and activate and we looking forward to the app elevating and including options like adding Buy Now with Walmart buttons to our website and Referral links.

Doesn't work. It seems like they didn't even test this app before launching it. When I try to connect I get "HTTP Status 400 – Bad Request".
