## Purpose

Use this component to enter a single expression into the orchestration's Message property. Orchestration Builder logs the contents of the Message property at runtime.

## <a id="section_2"></a>Template Availability

This component is available in these orchestration templates:

-   Synchronous
-   Asynchronous
-   Business Process
-   Home Card
-   Integration System
-   Custom Agent Action


## <a id="section_1"></a>Properties

Provide a meaningful <b>Reference Name</b> for the step as it will appear in your orchestration.

Use Expression Builder to provide a message. Click <b>Add Conditions</b> to specify conditions using Expression Builder functions.

You can use the <b>Condition</b> field to optionally specify a condition under which the message is logged at runtime. If the condition isn't met, the message isn't logged.
