Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Using the Process.PluginRequest Class

The Process.PluginRequest class passes input parameters from the class that implements the interface to the 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.
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.

Tip

This class has no methods.

Constructor signature:

1Process.PluginRequest (Map<String,Object>)

Here’s an example of instantiating the Process.PluginRequest class with one input parameter.

1Map<String,Object> inputParams = new Map<String,Object>();
2            string feedSubject = 'Flow is alive';
3            InputParams.put('subject', feedSubject);
4            Process.PluginRequest request = new Process.PluginRequest(inputParams);

Code Example

In this example, the code returns the subject of a Chatter post from a flow and posts it to the current user's feed.

1global Process.PluginResult invoke(Process.PluginRequest request) { 
2        // Get the subject of the Chatter post from the flow
3        String subject = (String) request.inputParameters.get('subject');
4        
5        // Use the Chatter APIs to post it to the current user's feed
6        FeedPost fpost = new FeedPost(); 
7        fpost.ParentId = UserInfo.getUserId(); 
8        fpost.Body = 'Flow Update: ' + subject; 
9        insert fpost; 
10
11        // return to Flow
12        Map<String,Object> result = new Map<String,Object>(); 
13        return new Process.PluginResult(result); 
14    } 
15
16    // describes the interface 
17    global Process.PluginDescribeResult describe() { 
18        Process.PluginDescribeResult result = new Process.PluginDescribeResult(); 
19        result.inputParameters = new List<Process.PluginDescribeResult.InputParameter>{ 
20            new Process.PluginDescribeResult.InputParameter('subject', 
21            Process.PluginDescribeResult.ParameterType.STRING, true) 
22            }; 
23        result.outputParameters = new List<Process.PluginDescribeResult.OutputParameter>{ }; 
24        return result; 
25    }
26}
