Calling REST API with Action

The purpose of this Action example is to illustrate how to use an Action to call a web service. In this example we will query the Perfion API to get a JSON API token for further querying, see Perfion API Reference for more information about the Perfion JSON REST API. 

To use this Action example you need to have the Perfion API installed and configured. You will also need to SHA256, Base64 encode your Perfion password, this can be done by creating a script to do so yourself or using an online tool. 

The example here can be execute in another action using the EXECUTE.ACTION command to retrieve the JSON API token for further querying in Perfion. 

A set of API actions for querying Perfion can be found for importing in the Excel file (APIActions.xlsx) attached at the bottom of this page. 

Sample data for building Action Map

Data must be adapted to your Perfion environment to work.

string url = Make( "{=$API}" ) + Make( "{=$params}" );
string requestType = Make ( "{=$type}" );

Sources["url"] = url ;
string postData = Make("{=$body}");
string ret = "";

StreamWriter requestWriter;

var webRequest = System.Net.WebRequest.Create(url) as System.Net.HttpWebRequest;
if (webRequest != null){
webRequest.Method = requestType ;
webRequest.ServicePoint.Expect100Continue = false;
webRequest.Timeout = 20000;

webRequest.ContentType = "application/json";
//POST the data.
if(webRequest.Method.Equals("POST")) {
using (requestWriter = new StreamWriter(webRequest.GetRequestStream())) {
requestWriter.Write(postData);
}
}
}

System.Net.HttpWebResponse resp = (System.Net.HttpWebResponse)webRequest.GetResponse();
Stream resStream = resp.GetResponseStream();
StreamReader reader = new StreamReader(resStream);

ret = reader.ReadToEnd();
Sources["_response"] = ret;
