Platform events are powerful tools that enable real-time communication within the Salesforce ecosystem and with external systems. These events serve as secure, scalable messages that contain data, allowing for instant publication and subscription.
Salesforce platform events enable the real-time exchange of event data, facilitating seamless integration between various platform components and external applications.
Platform events play a key role in Salesforce’s event-driven architecture. They allow users to define custom notifications that can trigger actions or updates across multiple systems.
This capability is handy for businesses seeking to automate processes, synchronize data, or respond promptly to changes in their Salesforce environment.
Creating a platform event in Salesforce is similar to defining a custom object. Users can name the event and add custom fields to capture the specific data they need to transmit.
This flexibility enables platform events to be adaptable to various business needs, ranging from tracking inventory changes to monitoring customer interactions.
Understanding Platform Events in Salesforce
Platform Events are a key part of Salesforce’s event-driven architecture. They let users share data quickly between Salesforce and other systems.
Definition and Purpose in Salesforce
Platform Events are messages in Salesforce that carry data about events. They work like a notice board. When something changes, Salesforce posts a notice. Other parts of Salesforce or external apps can view this notice immediately.
These events help different systems communicate quickly. For example, when an order ships, a Platform Event can notify the billing system immediately. This quick sharing of information helps businesses run smoothly.
Platform Events use an Event Bus. This bus is like a digital highway that moves data quickly and securely, ensuring that all the necessary systems receive the updates they need.
Comparing Platform Events to Other Salesforce Events
Platform events differ from other Salesforce events in several ways. They’re more flexible and can handle more data at once.
Unlike workflow rules, Platform Events can talk to systems outside of Salesforce. This makes them great for connecting different apps.
They’re also faster than traditional methods, such as polling. Instead of constantly checking for changes, systems just wait for Platform Events to arrive.
Platform Events can also be used with Apex triggers. This allows developers to add custom code that runs when an event occurs.
For big companies, there are High-Volume Platform Events. These can handle millions of events per day without slowing down.
Publishing and Subscribing to Platform Events in Salesforce
Platform events in Salesforce allow for real-time communication between systems. Publishers send event messages, while subscribers receive and process them. This enables seamless data exchange and integration.
How to Publish Platform Events in Salesforce
Salesforce offers several methods for publishing platform events. Apex code is a common method allowing developers to create and fire events programmatically. The REST API and SOAP API also support event publishing, making it easy to send events from external systems.
Process Builder and Flow can publish events based on record changes or user actions. This is useful for non-technical users to set up event-driven processes. When publishing, include all required fields and any optional fields with relevant data.
To publish events at scale, use the REST API with composite requests or the Bulk API. These methods help handle large volumes of events efficiently.
Methods to Subscribe to Platform Events in Salesforce
Subscribing to platform events can be done through various Salesforce tools. Apex triggers are a powerful way to respond to events, enabling custom logic to execute when specific events are received.
Flow and Process Builder can subscribe to events, enabling the creation of automated workflows without requiring code. These tools are ideal for business users who need to establish event-based processes.
The Pub/Sub API is an efficient option for real-time processing. It uses a streaming model to deliver events to subscribers quickly. CometD, a web protocol for real-time data pushing, is another choice for creating responsive applications.
External systems can subscribe using the REST API or SOAP API. This allows for integration with non-Salesforce applications, enabling various use cases across different platforms.
Integrating Platform Events with External Systems in Salesforce
Platform events allow Salesforce to connect with external systems. This integration enables real-time data exchange and synchronization between Salesforce and other applications.
Using Salesforce APIs for Integration in Salesforce
Salesforce offers APIs to integrate platform events with external systems. The REST API and SOAP API let developers programmatically create, publish, and retrieve platform events.
These APIs provide a secure way for external apps to send event data to Salesforce. Developers can use them to trigger actions in Salesforce based on events in other systems.
The Streaming API allows external systems to subscribe to platform events. This API uses a publish-subscribe model for real-time event notifications.
Platform Events in External Apps in Salesforce
External applications can work with Salesforce platform events using CometD. CometD is a scalable HTTP-based event routing bus that enables real-time data streaming.
External apps establish a CometD connection to Salesforce to receive platform events. They then subscribe to specific event channels. When events occur, Salesforce sends notifications to subscribed clients in real time.
External systems can also publish platform events to Salesforce. This allows them to trigger processes or update data in Salesforce based on external events.
Salesforce Event Messaging
Salesforce event messaging allows apps to communicate in real-time within and with external systems. It utilizes platform events to send and receive notifications about changes or significant events.
Transaction Behavior and Event Publishing in Salesforce
When you publish an event on a platform, Salesforce creates an event message. This message is separate from the transaction that triggered it. If the transaction fails, the event message will still be sent.
Publishing events returns a Database.SaveResult object. This object tells you if the publication was successful. You can check the results to see if any errors occurred.
Events are published asynchronously. This means the system doesn’t wait for the publication to finish before proceeding, which helps keep your Salesforce org running smoothly.
Event Retention and Consumption in Salesforce
Salesforce stores platform events for 24 hours. After that, they’re deleted, giving event consumers time to process them.
Event consumers are apps or systems that listen for and react to events. They can be inside Salesforce or external. Consumers can access events as soon as they’re published.
If a consumer misses an event, they can still get it within the 24 hours. This helps ensure important updates aren’t lost.
Notification with Platform Events in Salesforce
Platform events enable real-time notifications in Salesforce. When something important happens, an event can trigger immediate action.
For example, an event could notify sales reps when a new lead is assigned to them or alert customer service when a high-priority case is created.
Events can also trigger flows or processes in Salesforce, allowing for automated responses to specific situations. External systems can also listen for these events, enabling seamless integration with Salesforce.
Practical Applications of Platform Events in Salesforce
Platform events in Salesforce enable real-time data exchange and automation across systems. They offer flexible solutions for various business needs and integration scenarios.
Use Cases
Platform events can trigger actions when specific changes occur in Salesforce. For example, when creating a new customer account, an event can notify other systems to set up related records.
Events also help sync data between Salesforce and external apps. A retailer might use them to update inventory levels in real time as sales occur.
For customer service, platform events can alert agents about urgent cases. This speeds up response times and improves customer satisfaction.
Many companies use events for IoT device management. When a device reports an issue, an event can automatically create a service ticket.
Customization and Development in Salesforce
Developers can create custom platform events to fit unique business processes, allowing for tailored solutions that match specific company needs.
Apex, Salesforce’s programming language, can publish and subscribe to platform events, enabling complex automation within Salesforce.
Salesforce DX tools support working with platform events during the development process. Developers can easily test and deploy event-based features.
Platform events integrate well with Salesforce’s click-not-code tools. Admins can react to events without writing code using Process Builder or Flow.
Events can also enhance website functionality. For instance, they can update live dashboards or trigger web notifications based on Salesforce data changes.
