This is script is a little Proof of Concept, I wanted to fetch the data from zimbra REST API. You can find the API doc there. I didn't find much how to do it, that's why I'm publishing this script. This is not the dev repository so don't expect a nice commit log.
The comments are in French because they're intended for my coworkers and their mother tongue is French, but I'm sure you'll be able to understand what is happening :)
