The following optional parameters are supported to filter the result set:

+## Debugging
+Setting an environment parameter (`NODE_DEBUG=request`) will dump the HTTP requests from the client library and responses received to `stderr`.
+
+```
+NODE_DEBUG=request node script.js
+```
+
+This parameter can also be set dynamically at runtime, provided this happens before the `openwhisk` module is required.
+
+```
+process.env.NODE_DEBUG='request';
+var openwhisk = require('openwhisk');
