LINE Store offers LINE users, a library of emojis that user can purchase and use when communicating on the LINE messenger app. When user sends LINE emoji to Official Account, it will be received as a description rather than an image.
If you want to send LINE emoji to LINE users, you can choose from this emoji list.
LINE emoji is not a message type in Conversation API but it is possible to send message by overriding with Explicit Channel Message.
