Response card in Amazon lex

Question

I am using Amazon lex to build a chatbot. When I was trying to build a response card using lambda function as a validation code-hook, I observed that the maximum number of buttons in a response card must be five. Can we increase the number of buttons in a response card?

Answer 1

No, we cannot have more than the limit.
In slack you can have 5 buttons and in messenger you can have 3 buttons, max.
If you are giving more than the limit you won't get error but only first 3 (or 5) will be shown.
