How to concatenate a string in a Pentaho box?

I am new to Pentaho (installed today). I was able to do a basic transformation in Spoon. Now I need to do something, and I can’t figure out how to do it.

my input looks like

2012-09-17|garima|fbhjgjhgj87687jghgj88jgjj|garima#1347868164626|::ffff:120.56.132.137

The third field is the identifier for which I need to get some information from the REST API

http://api.app.com/app/api/v1/feature/fbhjgjhgj87687jghgj88jgjj

What do I need to do in Spoon to do this?

In addition, the data will be returned in json format. How do I make it out?
