These flows are designed to handle event-driven architecture, enabling systems to communicate and react to specific occurrences within the Salesforce ecosystem or from external applications.
A platform event is a custom message that contains data about a particular occurrence. When an event is published, Platform Event-Triggered Flows can subscribe to these events and execute automated actions based on the event data received. This creates a robust mechanism for building reactive, loosely-coupled integrations.
Key characteristics of Platform Event-Triggered Flows include:
1. **Asynchronous Processing**: These flows operate asynchronously, meaning they run in the background after an event is published, allowing the main transaction to continue uninterrupted.
2. **Real-Time Responsiveness**: The flow triggers as soon as the platform event is published, enabling near real-time automation responses.
3. **Scalability**: Platform events are designed to handle high volumes, making them suitable for enterprise-level integrations and complex business processes.
4. **External Integration**: External systems can publish events to Salesforce, triggering flows that process incoming data and update records accordingly.
Common use cases include:
- Processing data from external systems
- Coordinating actions across multiple Salesforce orgs
- Handling high-volume data processing scenarios
- Building notification systems
- Managing complex integration workflows
To create a Platform Event-Triggered Flow, administrators first define a custom platform event object with relevant fields. Then, using Flow Builder, they select the Platform Event trigger type and specify which event the flow should subscribe to. The flow can then include various elements like assignments, decisions, loops, and data manipulation actions.
These flows are essential for modern Salesforce implementations requiring event-driven automation and seamless integration capabilities between Salesforce and external applications.
Platform Event-Triggered Flows: Complete Guide for Salesforce Administrators
Why Platform Event-Triggered Flows Are Important
Platform Event-Triggered Flows represent a powerful automation capability in Salesforce that enables real-time, event-driven architecture. They allow administrators to respond to events from both internal Salesforce processes and external systems, making them essential for building scalable, loosely-coupled integrations. Understanding this feature is crucial for the Salesforce Administrator exam as it demonstrates mastery of advanced automation concepts.
What Are Platform Event-Triggered Flows?
Platform Event-Triggered Flows are a type of Flow that automatically runs when a platform event message is received. Platform events are part of Salesforce's event-driven messaging architecture, allowing different systems to communicate through a publish-subscribe model.
Key characteristics include: - They subscribe to a specific platform event - They execute asynchronously when an event is published - They can process events from internal Salesforce processes or external applications - They support high-volume event processing - They run in system context
How Platform Event-Triggered Flows Work
Step 1: Platform Event Definition First, a custom platform event must be created in Setup under Platform Events. This defines the structure of the event message, including custom fields that carry data.
Step 2: Flow Creation In Flow Builder, select 'Platform Event-Triggered Flow' as the flow type. You then choose which platform event will trigger the flow.
Step 3: Event Publishing Events can be published through: - Apex code using EventBus.publish() - Flow actions - Process Builder - External systems via the Salesforce API
Step 4: Flow Execution When an event is published, all active flows subscribed to that event receive the message and execute their logic. The flow accesses event data through the $Record global variable.
Common Use Cases
- Integrating with external systems in near real-time - Triggering actions based on changes in external applications - Building decoupled automation that responds to business events - Processing high-volume notifications efficiently - Creating audit trails or logging mechanisms
Key Limitations to Remember
- Platform events are asynchronous, so timing is not guaranteed - They do not support transaction control in the same way as record-triggered flows - Event messages are retained for 72 hours by default (24 hours for standard retention) - Cannot be debugged in the same way as other flow types - Run in system context, meaning they bypass user permissions
Exam Tips: Answering Questions on Platform Event-Triggered Flows
1. Understand the Publish-Subscribe Model Questions often test whether you understand that publishers and subscribers are decoupled. The publisher does not need to know who is listening.
2. Know When to Use Platform Events vs Other Automation If a scenario involves external system integration or event-driven architecture, Platform Event-Triggered Flows are likely the answer. For standard record changes, Record-Triggered Flows are more appropriate.
3. Remember Asynchronous Nature Platform Event-Triggered Flows do not run in the same transaction as the publishing action. Questions may test this by asking about transaction boundaries.
4. Recognize System Context Execution These flows run with system-level permissions. Exam questions may present scenarios involving security considerations.
5. Identify Event Retention Questions Know that platform events have limited retention periods. This affects replay scenarios and troubleshooting.
6. Look for Integration Keywords When exam questions mention external systems, real-time notifications, or decoupled architecture, consider Platform Event-Triggered Flows as a potential answer.
7. Distinguish from Change Data Capture Platform events are custom-defined, while Change Data Capture events are system-generated for standard and custom object changes. Know the difference for exam scenarios.
Practice Scenario
If an exam question describes a situation where an external inventory system needs to notify Salesforce when stock levels change, and Salesforce should update related opportunity records, the correct answer would involve creating a Platform Event-Triggered Flow that subscribes to a custom platform event published by the external system.
