Overview of Platform Events in Salesforce
Welcome to our comprehensive guide on platform events in Salesforce. Whether you’re a seasoned Salesforce user or just starting out, understanding the power and functionality of platform events is essential for delivering real-time data and driving efficient business processes.
Understanding the concept of event-driven architecture
Event-driven architecture (EDA) is a paradigm that allows applications to respond to events or changes in real-time, rather than relying on traditional request-response mechanisms. In an EDA, events are the central building blocks that trigger actions or workflows within an application. This architecture enables organizations to build highly responsive and scalable systems that can react to business changes instantly.
Platform events serve as the backbone for event-driven architectures in Salesforce. They provide a standardized way to publish and subscribe to events within the Salesforce ecosystem. By leveraging platform events, you can build applications that respond to business changes in real-time, improving agility and enabling faster decision-making.
Platform events are based on the publish-subscribe pattern, where publishers generate events and subscribers consume them. This decoupled nature allows multiple subscribers to react to the same events, ensuring flexibility and scalability in your application design. Additionally, platform events are durable and reliable, meaning that they are stored and delivered even if there are system disruptions or outages.

How to create and manage Platform Events in Salesforce
Creating and managing platform events in Salesforce is a straightforward process. Here’s a step-by-step guide to get you started:
1. Define the event schema: Start by defining the structure of your platform event. This schema determines the fields and data types that the event will contain. Think about the information you want to capture and the fields that are relevant to your use case.
2. Create a platform event object: Once you have defined the event schema, create a platform event object in Salesforce. This object represents the event and holds the actual data when an event is published. Define the fields on the object based on the event schema.
3. Publish events: To publish events, you can use the Salesforce API or declarative tools like Process Builder or Flow. Determine the conditions or triggers that should initiate the event and define the actions to publish the event. You can also include additional data in the event payload, such as related records or metadata.
4. Subscribe to events: Subscribing to events allows you to consume and process the published events. Define the criteria for subscribing to events and specify the actions or processes that should be triggered when an event is received. You can subscribe to events using Apex triggers or declarative tools like Process Builder.
5. Monitor and manage events: Salesforce provides tools to monitor and manage platform events. You can track event metrics, such as event delivery and consumption, to ensure that events are being processed correctly. Additionally, you can use event monitoring to troubleshoot any issues and optimize your event-driven processes.
