The URL.

requestHttpRequestYesAn HttpRequest object containing headers, cookies, parameters.

Return type

Variable return type - depending on the left hand side operator type. EG: can be a custom struct, string etc.

Example

You can check whether something exists in the external system. For instance, you can check whether a certain user exists in Salesforce and get the user parameters if such exist.

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;


Note

The request is required, and at least a http header should be set. For example, you can set the "Content-Type" header.
