Within CSS Partners such as Bigshopper, a Merchant Center account is automatically verified and claimed. Unlike via Google CSS, where it must be demonstrated that you are the owner of a Merchant Center (through verification). However, it is not possible to change the domain name (which is automatically claimed and verified) with a CSS Partner, for example if there is a name change. Should this be the case, please contact us. We ensure that the right people within Google change the domain name to avoid downtime of your account. This applies only if the entire domain name changes in terms of name.
