When you connect your GeekSeller Walmart DSV panel with ShipStation, you need to create a custom store in ShipStation. All the details of the integration steps are explained in your GeekSeller Walmart DSV Panel under Extensions > ShipStation.
During the store set up process on ShipStation you may receive this error:
We received an error testing the Custom store: Invalid XML. Error: ‘Data at the root level is invalid. Line 2, position 1.’ We received: ‘
Error: Ship Nodes not selected
This error means you did not insert Distribution Facilities information into GeekSeller panel (see step 3 of the DSV onboarding post). You will also need to select those distribution facilities, as sources of orders in Step 1 of the GeekSeller <> ShipStation extension located in your GeekSeller Walmart DSV Panel under Extensions > ShipStation.
