Consider the following rules and guidelines when you create a Salesforce Streaming Event process:
•You can only use Salesforce Streaming Event Connector to subscribe to or publish messages to Salesforce standard platform events and not process objects.
•If you add a Wait step to a process to subscribe to Salesforce custom platform events, PushTopic queries, and change events, you must ensure that the wait period is earlier than 40 seconds. If the wait period exceeds 40 seconds, you might encounter a message loss. Add a Milestone step for an early reply and to prevent message loss.
•When a process that consumes Salesforce streaming events fails, the process is incorrectly triggered two more times.
