# The legacy Instances API (v3 and below) is deprecated

ironSource LevelPlay API deprecated /partners/publisher/instances/* without giving a shutdown date yet.

Legacy versions 3 and below are deprecated as of March 2025 without a specified shutdown date. The deprecation applies to calls targeting /partners/publisher/instances/* endpoints. Once retired, requests sent to these legacy endpoints fail.
