API

Sending messages

The Channels API supports many of the features of Line; however, due to the omni-channel nature of the API, there may be some differences between the Channels API message and the native Line API.To send a Line message, you must have an active Line channel and perform an HTTP request to the following endpoint with a valid access key
POST
/workspaces/{workspaceId}/channels/{channelId}/messages
Send a message to a channel

You can send messages to users who have added your LINE Official Account as a friend or in group chats and multi-person chats that your LINE Official Account has joined. Additionally, you can send messages to users who have sent a message to your LINE Official Account within the past seven days.
The Channels API supports many of the features of Line; however, due to the omni-channel nature of the API, there may be some differences between the Channels API message and the native Line API. Here is an overview of the Line message types and Channels API message types:
