Check Connection & Confirm
After creating the Walmart Instance in your odoo store, Please Confirm the connection to make sure everything is fine between Odoo and Walmart. Once it gets configured successfully you are all set to use the Walmart Connector.
In some cases, if the connection fails, Then please check & verify the Client Key and Secret Key of your Walmart by clicking Walmart Credentials. And again add your latest Client Key and Secret Key in odoo instances if it is not already.
