Implementing the Process.Plugin Interface

Process.Plugin is a built-in interface that allows you to pass data between your organization and a specified flow.

We recommend using the @InvocableMethod annotation instead of the Process.Plugin interface.

The interface doesn’t support Blob, Collection, and sObject, data types, and it doesn’t support bulk operations. After you implement the interface on a class, the class can be referenced only from flows.
The annotation supports all data types and bulk operations. After you implement the annotation on a class, the class can be referenced from flows, processes, and the Custom Invocable Actions REST API endpoint.
Legacy Apex actions aren’t supported in auto-layout in Flow Builder. Legacy Apex actions are only available to be added in free-form in Flow Builder. Existing actions can be edited in both auto-layout and free-form mode.

Tip

The class that implements the Process.Plugin interface must call these methods.

Name	Arguments	Return Type	Description
`describe`		`Process.PluginDescribeResult`	Returns a `Process.PluginDescribeResult` object that describes this method call.
`invoke`	`Process.PluginRequest`	`Process.PluginResult`	Primary method that the system invokes when the class that implements the interface is instantiated.

Example Implementation

The following is a test class for the preceding class.
