struct serverInfo{
	string baseUrl;
	string version;
	number [] versionNumbers;
	string deploymentType;
	number buildNumber;
	string buildDate;
	string serverTime;
	string serverTitle;
}

//Create request
HttpRequest request;
HttpHeader authHeader = httpBasicAuthHeader("admin", "admin");
request.headers += authHeader;

//Post data and get response
serverInfo si = httpGet("http://localhost:8080/rest/api/2/serverInfo?doHealthCheck=false", request);
return si.baseUrl;
