Passing Data to a Flow Using the Process.Plugin Interface

Process.Pluginis a built-in interface that allows you to process data within your organization and pass it to a specified flow. The interface exposes Apex as a service, which accepts input values and returns output back to the flow.
We recommend using the @InvocableMethod annotation instead of the Process.Plugin interface.
  • The interface doesn’t support Blob, Collection, sObject, and Time data types, and it doesn’t support bulk operations. Once you implement the interface on a class, the class can be referenced only from flows.
  • The annotation supports all data types and bulk operations. Once you implement the annotation on a class, the class can be referenced from flows, processes, and the Custom Invocable Actions REST API endpoint.

When you define an Apex class that implements the Process.Plugin interface in your organization, the Cloud Flow Designer displays the Apex class in the Palette.

Process.Plugin has these top-level classes.

When you write Apex unit tests, instantiate a class and pass it into the interface invoke method. To pass in the parameters that the system needs, create a map and use it in the constructor. For more information, see Using the Process.PluginRequest Class.
