Activities can have properties. These properties can be made available to visual workflow composers by annotating them with ActivityInputAttribute and ActivityOutputAttribute.

These attributes have more properties:

• Name: Controls the technical name of the property.
• Label: Controls the display text when rendering this property on a form in the activity editor.
• Hint: Controls the hint text displayed underneath the field editor in the activity editor.
• SupportedSyntaxes: Controls what syntaxes are available to use when specifying a value for this property through the activity editor.

The results of this activity after executing the request are as shown below:
