Use the Messaging API to build bots that provide personalized experiences for your users on LINE.
Note: As of April 18, 2019, the existing LINE@ account plans have been consolidated into the new LINE official account plans. This LINE Developers documentation mainly describes features available to LINE official accounts. For more information about migrating LINE@ accounts to LINE official accounts, see Migration of LINE@ accounts.
How it works
The Messaging API allows for data to be passed between your bot server and the LINE Platform. Requests are sent over HTTPS in JSON format.
- The user sends a message to the LINE official account.
- The LINE Platform sends a webhook event to the webhook URL of the bot server.
- According to the webhook event, the bot server responds to the user through the LINE Platform.

Using LINE Beacon, you can configure your LINE official account to interact with users whenever they enter the range of a beacon. For more information on using beacons, see Using beacons.
Use account link
By using the account link feature, providers (businesses and developers) can securely link the existing user accounts from their service with accounts belonging to LINE users that have friended providers' LINE official account. For more information, see Linking user accounts.
Get the number of sent messages
This only returns the number of messages sent with the Messaging API, not LINE Official Account Manager.

To create a bot, create a Messaging API channel in the LINE Developers console. A LINE official account is created together with the channel.
