A version 2 of the Object API has been introduced which supports now also write operations. This will allow extending the use case of the object API from only consuming system integrations to writing back updates to a record in a similar fashion as you would read the data from Product 360. In order to streamline the usability of the API, also the payload of the READ requests has been adjusted and is not compatible with V1 payloads any longer. Please find all details of the new Object API version in the

Informatica MDM - Product 360 REST Service API

guide.
