 ## Engaging a custom handler based on API Properties
 
-In API Manager, you can implement and engage custom handlers to customize the default mediation flow of API requests. See [Writing a custom handler]() for more information. The [API properties]({base_path}/learn/design-api/create-api/adding-custom-properties-to-apis/) can be used to conditionally engage these custom handlers for APIs.
