In many cases, there are groups of people that need to be notified when an event happens. Namings and setup may vary after the needs you have.

In this tutorial, we will describe how the members of the group Accounting will be notified when the event Billing is thrown.

Step by step 

1. Create a group in JIRA or (fetch from LDAP; AD) named Accounting 
   1. assign or load members into the group
       
2. Create an Event under System → Events named Billing
   
   
3. Create a custom field named Group of type Group Picker (Single) 
   
4. Add the group custom field to the screen of your project
5. Edit the workflow of the project, in our example we will have a transition called Send to accounting 
   
   
6. Click Postfunctions for the Send to accounting transition
7. Add a postfunction that sets the Group field to Accounting (if the group is set before this manually then this step is optional or use default value on the custom field to always set that value)
8. Change the last Fire event to Billing
   
   OK time to hook this into Inbox for JIRA!
9. Goto Inbox Global settings, Manage Apps → Inbox Settings
10. Enable the custom field Group this will make the Group field show in the checkbox section
11. Select the Billing event for the Group field in the checkbox section
    

That is all! All billing events will now trigger Inbox notifications for the Accounting group.
