Deprecation Schedule

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.

What happens when a version sunsets?

When a version is sunset all incoming requests are rejected with an HTTP 403: Forbidden error response. These errors are accompanied by a message alerting users that the version is no longer supported:

{
  "error": {
    "errors": [
      {
        "domain": "global",
        "reason": "forbidden",
        "message": "3140 : Version v2.x of the DCM/DFA Trafficking and Reporting API is no longer supported. Please upgrade to the latest version of the API."
      }
    ],
    "code": 403,
    "message": "3140 : Version v2.x of the DCM/DFA Trafficking and Reporting API is no longer supported. Please upgrade to the latest version of the API."
  }
}

After some time, the version is fully deactivated and becomes unreachable. At that point, all requests against the version receive a generic HTTP 404: Not Found error response.
