    With the consolidation of LINE@ account plans into LINE official plans, we changed the functionality of the LINE Developers console and the Messaging API as follows:

    Changes in the LINE Developers console

    Type of created accounts

    When you create a Messaging API channel in the LINE Developers console, a LINE official account is created instead of a LINE@ account.

    For more information, see Migration of LINE@ accounts. Existing LINE@ accounts will be migrated to LINE official accounts sequentially.

    Privacy policy and terms of use

    Now you can set your own privacy policy and terms of use for your app in your LINE Login and Messaging API channels.

    In the future, we will add links to your privacy policy and terms of use for your app in the user consent screen of LINE Login or your LINE official account.

    Enhanced Messaging API features

    Bots associated with new or migrated LINE official accounts can use the following features regardless of applied plans:

    Bots associated with LINE@ accounts cannot use these features depending on applied plans.

    For more information, see the Messaging API reference.

    Migrating your LINE@ account under the Developer Trial plan

    We will consolidate the LINE@ account plans into the new LINE official account plans.

    After mid-June, 2019, we will migrate the existing LINE@ accounts under the Developer Trial plan to LINE official accounts. The free plan will be applied to the migrated LINE official accounts.
