You can pass JSON or XML sample data to test data mapping between an external tool and
 Modifiers added to a One-Step Action. This enables you to verify that the One-Step Action is valid before you send events from an external tool. 
                                                    
                                                        To test One-Step Actions assigned to webhook endpoints: 
                                                    
                                                    
                                                        - Open the Webhooks Manager, and then edit the webhook endpoint you want to test. 
                                                        
- Select the Run One-Step button. 
                                                        
- Paste valid JSON or XML that you expect to be sent from the external tool to the CSM webhook endpoint. 
                                                            
                                                        
- Select Run. 
                                                        
- View the results in the bottom of the dialog. If the One-Step Action and Modifiers are not configured correctly, review the
 messages and adjust the Modifiers in your One-Step Action as needed.
