The Salesforce enterprise messaging platform offers the benefits of event-driven software architectures. Platform events are the event messages (or notifications) that your apps send and receive to take further action. Platform events simplify the process of communicating changes and responding to them without writing complex logic. Publishers and subscribers communicate with each other through events. One or more subscribers can listen to the same event and carry out actions.

Platform events are defined in Salesforce in the same way that you define custom objects. Create a platform event definition by giving it a name and adding custom fields. The custom fields define the data that is sent in the event messages. Platform events support a subset of field types in Salesforce.
