Introducing Flex Message, a new message type for LINE Messaging API

A new type of message has been added to the LINE Messaging API, Flex Message. We’ve been using a template-typed message in which you could place plain text, stickers, images, media types like videos, buttons and URLs. This type is quite useful for where the user had to select an option from available options, but there were restrictions such as the maximum number of buttons allowed, which is 4, for the button template, or the order in which you had to arrange the elements for a layout — title, content, and buttons.
