platform-events

What problem does it solve?

Platform events provide a scalable way to decouple Salesforce applications by defining custom event objects with __e suffix and enabling event-driven communication across Apex, Flows, REST, and external subscribers.

Core Features & Use Cases

• Event Definition & Metadata: Define reliable event schemas with fields and publish behavior.
• Publish & Subscribe: Publish events from Apex, Flow, REST, and subscribe via Trigger, Flow, or external subscribers using CometD or Pub/Sub APIs.
• Replay & Reliability: Use replay IDs to resume processing and implement idempotent processing patterns.
• Error Handling: Patterns for dead-lettering and graceful failure without blocking transactions.
• Use Case: Build an order processing workflow that publishes an Order_Placed__e event and reacts to it asynchronously.

Quick Start

Instantiate the first Order_Placed__e event in your Salesforce org using the provided Apex snippet.
