Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Object Interfaces

An object interface defines the business logic that an object implements. The object that implements the interface, called the implementor, stores the data and implements the business logic.

An API that accepts a parameter with an object interface data type can accept any implementor of the object interface. For example, /calculate-price accepts the SalesTransaction object interface. You can use any implementor of SalesTransaction, such as an Order object, in the /calculate-price request.
