So, I'm tasked with a project and need some general guidance. Basically, here is what I am trying to accomplish...

1. Our Org has a custom object that when created, I would like to fire off a trigger
2. The Trigger (or class that the trigger calls) would then find the subscriber (because they should already exist in Exact Target) and add that subscriber to an existing List in Exact Target. 

My question is... Can this be done with Apex code? I've read the documentation around adding subscribers to a list using the API but I haven't found any examples using APEX. I guess the other option would be to Invoke a Callout?

Thoughts? Thanks in advance for your time and effort.
