This image shows the Server Identification tab in the Create Service Connection dialog. The top section shows GET selected for the method and https://restcountries.com/{version}/lang/{language} for the REST endpoint URL. The https://restcountries.com/{version} portion of the URL is grayed out, because it can't be modified; it is coming from the server's instance URL. The /lang/{language} portion of the URL is not grayed out, meaning that {language} can be defined as a path parameter.

In the Server Identification section, the Instance URL is shown as https://restcountries.com/{version}. The Description is shown as "V3.1".

In the Server Variables section, "version" is shown for the variable name, there is no description, and the default value has been set as "v3.1".

A closed Options menu icon is shown to the right of the Default Value setting.
