ResponseCard - Amazon Lex

We recommend using Amazon Lex V2 to take advantage of the latest features. Documentation for Amazon Lex V2 may be found here.


If you configure a response card when creating your bots, Amazon Lex substitutes the session attributes and slot values that are available, and then returns it. The response card can also come from a Lambda function ( dialogCodeHook and fulfillmentActivity on an intent).
