Integration
Walmart Marketplace integration
mPorts OMS connects to Walmart Marketplace, covering order flow, inventory and price updates, item feeds, and returns.
Integration status
Built and tested against the documented contract. Live readiness for your account is confirmed during onboarding rather than assumed.
What data flows
Orders in
Orders are pulled from Walmart; they are not created there by mPorts.
Order actions out
Accept, ship, cancel and refund.
Inventory and price
Read and update, plus inventory and price feed submission.
Items
Read items, submit item feeds, retire items.
Returns
Returns are read back.
Feed status
Submitted feeds are followed to a result.
What this automates
Work that would otherwise be done by hand in the Walmart Marketplace seller interface, one order at a time.

What this integration does not do
-
Creating orders on Walmart
Marketplace orders flow in; mPorts does not originate them.
-
Label upload
Not part of this integration.
-
Tracking upload as a separate call
Tracking travels with the ship action.
-
Shipping method selection
Not exposed by this integration.
-
Which location ships it
Orders pulled from this channel do not say where they should ship from.
How authorization is handled
OAuth 2.0 client credentials, exchanged for a bearer token. Credentials are held by the integration layer; they are never stored in the OMS or shown in the interface.
Questions buyers ask
- Which mPorts OMS capabilities use this?
- Orders, Inventory, Fulfillment and Shipping all draw on it. The integration is infrastructure beneath those capabilities rather than a product of its own.
- Is this integration live for our account?
- That is confirmed during onboarding against your own credentials and catalog. We would rather check than assume, because the answer depends on your account's configuration as much as on the integration.
