Merge's Unified API has introduced an "ignore objects" function that allows customers to specify what end-user data is stored in Merge's servers, providing a way to comply with security or data storage concerns. This feature sets ignored models and related models to a 'null' value in Merge's servers, ensuring that even if data is sent from a third-party application, it will not be saved. The "ignore" function is preferred over permanent deletion because Merge regularly polls and normalizes data from various vendors, and deleting data could result in it being pulled again later. By using "ignore", customers can trust Merge to help them stay compliant with user requests and boundaries, and the feature scales as new models and features are added. The ignore objects feature can be used in various scenarios, such as when a recruiting candidate doesn't want their data stored or when a customer no longer wants their data stored by Merge.
