On occasion, it might be helpful for us to have access to your Walmart Seller Center. If you're asked to add Listing Mirror employee to your account, here are the steps to accomplishing that.
From the settings dropdown, select User Management
Under User Management, click Add New User in the top left of the section.
Add the first name of the LM employee, last name as Listing Mirror, and firstname.lastname@example.org for the email address.
For "role", our preference is to have you select Admin so we can access anything we might need to investigate.
Click "Add User", and we'll get an email that an account has been created.
