Use Kotlin scripts and Clova SDK to build your Clova extension
1 like1,500 views
The document discusses using Kotlin scripts to create a Clova client. It shows how to evaluate Kotlin code from a script using a ScriptEngine to define a Clova client configuration with launch, intent, and session ended handlers. The Clova client created in the script can then be used to handle Clova requests and responses.

val value = request.intent.slots["number"]?.value
