Access Data Outside Salesforce with Processes and Flows via External Objects
Where: This change applies to Lightning Experience and Salesforce Classic. Salesforce Connect is free for Developer Edition and available for an extra cost in Enterprise, Performance, and Unlimited editions.
Why: For example, when an order is updated, a third-party order management system publishes the platform event message for Order Status. When a process receives the event message, the process matches the order reference number of an external order record with the order reference number of the event message. This example assumes that the platform event and external object are defined in your org.
When Salesforce data is modified in an event process, we need to start a new transaction before we can update data outside Salesforce. Scheduled actions let us do just that. To update the external data as soon as possible, set the schedule to 0 Hours from now.
How: When you select an object for a process or a flow to access, the standard, custom, and external objects are displayed as options.
