Sample Process.Plugin Implementation for Lead Conversion

In this example, an Apex class implements the Process.Plugin interface and converts a lead into an account, contact, and optionally, an opportunity. Test methods for the plug-in are also included. This implementation can be called from a flow via a legacy Apex action.

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.
  • You can customize how invocable actions created with @InvocableMethod appear in Flow Builder by using the InvocableActionExtension metadata file. Control parameter order, add picklists, create custom headers, and build partial custom property editors.
