Chatbot (Messaging API)

Messaging API is an API that makes it more convenient to communicate with LINE users on your LINE Official Account.

End-user benefits

Messaging API

You can use the service in the familiar LINE chat room.

End users can use a variety of services in the familiar LINE chat room. There are more ways for end users to communicate with the operator of the LINE Official Account than just typing text in the LINE chat room, such as sending images, location information, or using the quick reply button displayed at the bottom of the chat room.

Rich Menu

You can instinctively use the functions of the LINE Official Account.

The rich menu of the LINE Official Account is one of the easiest interfaces to use, as it can be operated intuitively with just a tap of a button.

Service provider benefits

Messaging API

Speedy and detailed communication

You can use the Messaging API to provide detailed services for each end user.

Use the Messaging API for basic interactions that don't require operator response, such as pre-questions and surveys before providing a full-fledged service.

You can communicate with a number of users at the same time.

Targeted and efficient message delivery

You can send messages at any time to end users who have added your LINE Official Account as a friend.

Depending on the target of the message, you can use push messages (one-to-one), multicast messages (one-to-many), narrowcast messages (one-to-many: narrowed delivery with complex conditions), or broadcast messages (one-to-many: all friends).

For example, you can send push messages or multicast messages to send a special message only to end users who have purchased a product.

Narrowcast messages are recommended for sending messages by age or region.
