Answer 1

The lookback toolkit was an experimental toolkit and is not fully supported. https://github.com/RallyTools/Rally-Lookback-Toolkit

I doubt it contains support for api keys. According to the docs though you should just use setCredentials

https://github.com/RallyTools/Rally-Lookback-Toolkit#rally-lookback-api-toolkit

.setCredentials("username", "password")

Can use API Key for the Lookback API. Have to set this in the HTTP Header.

Import

import org.apache.http.Header;
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicHeader;

Code

Header header = new BasicHeader("ZSESSIONID", "_MYRALLYKEYLKEY01234567890ABCDEFGH");
HttpClient httpClient = HttpClients.custom().setDefaultHeaders(Collections.singleton(header)).build();
LookbackApi lookbackApi = new LookbackApi(httpClient);
