v201204 of the DFP API has launched and is ready for you to explore. In this version, we’ve added 
custom fields, 
expanded team and user functionality, and updated the 
conversion reports columns. A full list of features can be found on our 
release notes page.
Custom fieldsCustom fields is a new feature to the API that lets you add attributes to entities, such as orders and line items. For example, you can add your own 
field to a 
line item that would let salespeople add comments as a 
string. Those comments would then be placed into 
custom field values that are 
added to each line item.  Support for custom fields will be coming or the DFP UI soon, but if you have this feature enabled on your network now, you’ll be able to start working with them right away.
Teams changesThe way in which users are added to teams has changed starting in v201204. In previous versions, users were added to 
team objects directly. Now, you can 
associate users and teams, much like 
line items and creatives. The new associations will also let you define 
per user permissions, such as only letting some users have 
read-only access.
Version deprecation reminderAs a 
reminder, we are retiring support for v201103, v201104, and v201107 on 
May 11th. If you haven’t upgraded yet, now would be a great time.
Our next hangout is 
May 9th and we’d love to see you there. As always, let us know if you have any questions on our 
forum.
