Does the Conversation API support LINE Flex Message?

[Donna_M]

LINE Flex Messages are messages with a customizable layout. You can customize the layout freely based on the specification for CSS Flexible Box (CSS Flexbox) LINE provides a Flex Message Simulator that you can use to check the layout of your message.

LINE Flex Message is not a message type in Conversation API but it is possible to send Flex Message by overriding with Explicit Channel Message.

To do that, you can follow these steps:

1. Use the LINE's Flex Message Simulator to design your message
2. Copy the JSON from the simulator
3. Use Transcoding API to transcode generic message format to LINE.
4. Send messsage by overiding with Explicit Channel Message with the transcoded message.

Another alternative is to use another message type provided by the Conversation API. Sinch provides a Message Composer tool on the dashboard that would help you to easily build a message and visualize it in any social channels provided by the Conversation API.
