LinkedIn will sunset Marketing API version 202511 (November 2025) on November 16, 2026, according to its Microsoft Learn migrations page; calls that still send Linkedin-Version: 202511 after that date get an error response, so integrations need to move to a newer version header, the latest being 202610.
