Trailhead Module: Platform Events

Module Home

Deliver custom notifications within the Salesforce platform and in external apps.

1. Understand Event-Driven Software Architecture
2. Define and Publish Platform Events
3. Subscribe to Platform Events

Notes:

• You can publish more than one event by adding the event instance to a list. Then pass the list to EventBus.publish()
• For Process Builder or Flow's, select the event (shows up like a SF object/record) from Record Type, or Create Record
• Can publish events via the API
  • Endpoint: /service/data/v40.0/sobjects/{Event_Object__e}/
  • Sample POST body:

    {
        "Location__c" : "Mountain City",
        "Urgent__c" : true,
        "News_Content__c" : "Lake Road is closed due to mudslides."
    }
    

  • Sample Response:

    HTTP/1.1 201 Created
    {
        "id" : "e00xx000000000B",
        "success" : true,
        "errors" : [ ],
        "warnings" : [ ]
    }
    

• You can publish an event in SOAP API through the create() call or in Bulk API using batch jobs
• Use Triggers to subscribe to events. ONLY SUPPORTS after insert
  • trigger TriggerName on Custom_Event__e (after insert) {
• Event triggers are run at System level and Asynchronously, and it's own execution process in Automated Process entity
• Can't see Event Triggers debug log in dev console
• Subscribe to Platform events in Flows, use the Pause Element
