Campaign Manager 360 API v4 Sunset Reminder

Campaign Manager 360 API v4 will be sunset on February 26, 2026. Starting on this date, all v4 API requests will begin to fail. If you’re still using this version, we strongly encourage you to migrate to v5 as soon as possible to avoid service interruptions.

See the migration guide for details on how to upgrade. In most cases, you will just need to upgrade to the latest version of your preferred client library. We also recommend reviewing the release notes for important changes that may affect your implementation.

If you have questions, please contact Campaign Manager 360 API support.
