Deprecation Schedule

  • The Campaign Manager 360 API generally supports three versions concurrently.

  • A sunset date is announced when a new version is released, deprecating the previous version.

  • Deprecated versions remain available for approximately 7 months before being sunset.

  • After the sunset date, requests to deprecated versions are rejected with an HTTP 403: Forbidden error.

  • Eventually, sunset versions are fully deactivated and return an HTTP 404: Not Found error.

There will generally be three supported versions of the Campaign Manager 360 API at any given time. When a new version is released, a sunset date is announced for the previous version. A version is considered deprecated once a sunset date has been announced for it.

The deprecation period for most versions will be approximately 7 months. While deprecated versions remain available until the scheduled sunset date, users are encouraged to use the deprecation period to migrate to a newer version. After the sunset date, deprecated versions will no longer be available.


The following table lists the deprecation and sunset dates for each API version.
