Switching to GeekSeller from a Previous API Provider Thank you for choosing GeekSeller! We are glad to have you. Each step below includes a link that leads to detailed instructions. Invite GeekSeller to your Walmart Seller Center. Ask GeekSeller Support to import your existing products from Walmart.com. Contact us either via live chat or at firstname.lastname@example.org. Keep in mind that Walmart does not allow API integrations like GeekSeller to pull all data.
