# Commerce hostnames

When you deploy Sitecore Experience Commerce software, the installation scripts uses the CommerceServicesHostPostfix parameter value as the root domain name to append to Commerce service hostnames. The default CommerceServicesHostPostfix parameter value is "sc9.qa". As a result, the default Commerce service hostnames in a Commerce deployment are as follows:

• commerceauthoring.sc9.qa

• commerceops.sc9.qa

• commerceshops.sc9.qa

• commerceminions.sc9.qa

• bizfx.sc9.qa

### Note

In a Sitecore XC deployment, all five Commerce services are configured as subdomains of the “sc9.qa” domain by default.

The CommerceServicesHostPostfix parameter value that you specify during the installation process is stored in the Commerce Engine config.json file (for example, c:\inetpub\wwwroot\<CommerceAuthoring_SC9>\wwwroot\config.json). It is used to set anti-forgery cookies for the specified domain (for example "sc9.qa") so that the domain can be accessed on the BizFx site.

### Note

You cannot use a wild card character at the 1st level of the root domain when specifying the CommerceServicesHostPostfix parameter value. For example, the value *.qa or *.com is not a valid.
