+GitLab provides [[http://doc.gitlab.com/ce/api/ | a powerful API]] that lets you interact programmatically with a GitLab instance in order to automate a lot of things.
+This tutorial presents how to use the API of GitLab with [[https://www.python.org | Python]]. Of course you can use your favorite language.
+> For the examples below we will use the instance https://gitlab.example.org. Of course you can use https://gitlab.com.
 ====== Get the list of users registered in GitLab ======
+This first example is fairly easy and takes advantage of the [[http://doc.gitlab.com/ce/api/users.html | Users resource]].

 ====== Send an email to the members of a GitLab group ======
-Again, this is pretty easy. We will use the [[http://www.mutt.org/ | Mutt] email client in order to send the email.
+Again, this is pretty easy. We will need the [[http://doc.gitlab.com/ce/api/groups.html | Groups]] resource and the [[http://doc.gitlab.com/ce/api/users.html | Users]] resource.
-Mutt needs three parameters:
-  * the subject;
+In order to send the email, we will simply use the [[http://www.mutt.org/ | Mutt]] email client.
-  * the list of recipients (member of the GitLab groups);
-  * the message to be sent.
+The Mutt command will look like this:
 <code bash>
-$ mutt -s "Subject" `./get_recipents.py <group-id> /dev/null` < message.txt
+$ mutt -s "The subject" `./get_recipents.py <group-id> /dev/null` < message.txt

-Below you will find the script *get_recipients.py*:
+As you can see, Mutt needs three parameters:
+  * the subject of the email. Will be given in parameter;
+  * the message to be sent. Will be given through a Unix pipeline (//message.txt//);
+  * the list of recipients (members of the GitLab group). Will be given in parameter as the result of a Python script.
+As you can expect, the Python script will use the API of GitLab in order to get the list of recipients.

+A first request to the //Groups// resource returns the list of members in the group. The ''for'' loop iterates through these members in order to get their email.
+Only active users (//user["state"] == "active"//) will receive the email.
