Definition
A Salesforce messaging feature that enables event-driven architecture by allowing apps to publish and subscribe to custom events on the Platform Event Bus, facilitating real-time integration and loosely coupled communication between systems.
Real-World Example
a developer at Quantum Labs uses Platform Events to build a custom solution that extends the platform beyond its standard capabilities. They write clean, bulkified code for Platform Events, add comprehensive test coverage, and deploy it through a CI/CD pipeline. The new functionality handles 10,000 records without hitting governor limits.
Why Platform Events Matters
Platform Events are a Salesforce messaging feature that enables event-driven architecture by allowing apps to publish and subscribe to custom events on the Platform Event Bus, facilitating real-time integration and loosely coupled communication between systems. Each platform event is a custom event type with its own schema, defined by admins or developers. Publishers emit event records, and subscribers (Apex triggers, processes, flows, or external systems) receive them in near real-time.
Platform Events are Salesforce's modern approach to event-driven architecture. Compared to older patterns like polling or callouts on every change, platform events provide cleaner separation between publishers and subscribers, better scalability, and easier integration with external systems. Mature integration architectures use Platform Events for change notifications, async processing, and integration scenarios where loose coupling matters. They're often used alongside Change Data Capture (which automatically publishes events for record changes).
How Organizations Use Platform Events
- •TerraForm Tech — Built event-driven integration using Platform Events for cross-system notifications between Salesforce and their data warehouse.
- •Quantum Labs — Uses Platform Events for async processing patterns within Salesforce, decoupling publishers from subscribers.
- •CodeBridge — Treats Platform Events as the modern integration pattern, replacing older polling and callout approaches.
