Hey API developers,
Today we're really happy to announce that the Campaign Monitor API now supports the recently released segments functionality.
The new features are different enough to need a new API end point (v3.1), but if you don't need them - the previous endpoint (v3) will continue to function just fine.
The changes affect calls to create, update, add rule groups, and get details of segment. The new API details are on the segments page of our API docs.
We've also updated all our Ruby, Python, PHP, .NET & Java client libraries to support the new segments features.
