Using the Process.PluginDescribeResult Class

Use the Process.Plugin interface describe method to dynamically provide both input and output parameters for the flow. This method returns the Process.PluginDescribeResult class.

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.

Tip

The Process.PluginDescribeResult class doesn’t support the following functions.
