It's possible that you were approved to sell on Walmart but, for whatever reason, were not able to complete your registration in a timely manner. In this case, Walmart may have put your account on hold. If this is the case, please note that you are not prevented from continuing activities if you wish to resume the registration process.

Please make sure to use the unique registration link that Walmart e-mailed you to create and gain access to Seller Cener and resume the Onboarding process.
