    Users can no longer add LIFF apps to Messaging API channels

    LIFF v2 is scheduled to be updated with LINE Login as the core channel. Additionally, an upcoming change will prevent users from adding LIFF apps to Messaging API channels entirely. We strongly recommend users to add LIFF apps to the LINE Login channel.

    Scheduled change date

    Early February 2020


    Channel type Impact
    LINE Login channel Not affected.
    Messaging API channel After the specification change, LIFF apps cannot be added to the Messaging API channel. LIFF apps added to Messaging API channels at the time of specification change are still usable.
    note Do not add LIFF apps to the Messaging API channel

    At this time, users can add LIFF apps to the Messaging API channel. However, we strongly advise against it due to the following restrictions:

    • The bot link feature can't be used.
    • LIFF feature expansion may not be supported.
    • The LIFF app may not be usable in the future.

    LIFF apps added to the LINE Login channel have no restrictions and can use all LIFF v2 functions.

    Transition to the LINE Login channel

    To continue using the LIFF app added to the Messaging API channel, re-add the LIFF app to the LINE Login channel. Once re-added, LINE Developers console will issue a new LIFF app ID. As a result, please take note of the following:

    • If you're using LIFF v2, change the LIFF app ID specified in liff.init().
    • The LIFF URL used to launch LIFF(e.g.:line://app/1234567890-AbcdEfgh)will change.
    note Remove LIFF apps added to Messaging API channel

    To avoid confusion, delete the LIFF app added to the Messaging API channel after adding to the LINE Login channel.

    Endpoint for obtaining user statistics now available in Thailand (TH)

    New ID token verification endpoint released

    When your back-end server receives an ID token originating from LINE Login v2.1 or the LINE SDK, you should verify that the ID token is authentic.

    Previously, you had to use a JWT library or write your own decoding and verification code.

    After this release, you merely have to send an HTTP request to the verification endpoint to determine if an ID token is authentic.

    For instructions on verifying ID tokens, read Transfer ID token to back-end server.

    LIFF v2 released

    LINE Front-end Framework (LIFF) v2 is a platform for web apps provided by LINE.

    note Use the latest version of LIFF

    LIFF v1 will be deprecated.

    LIFF apps now run in external browsers

    With LIFF v1, LIFF apps ran only in LINE's in-app browser. With LIFF v2, LIFF apps can also run in external browsers. This means you can develop LIFF apps using the same development environment as general web applications.

    Get user profile and email

    Because compatibility with LINE Login v2.1 has improved, you can retrieve a user's ID and email address from the LINE platform. Your LIFF app can use this data to provide features related to user information and sending emails.

    Furthermore, you can use LINE Login (web login flow) even when your LIFF app is running in an external browser. This means you can use the same information even when the LIFF app is running in an external browser.

    Read QR codes

    You can start LINE's QR code reader and get the strings read by the user.

    Get LIFF app environment information

    You can get the following details about the environment in which your LIFF app is running:

    • Operating system in which the LIFF app is running (iOS, Android, external browser)
    • Whether the LIFF app is running in the in-app browser (true, false)
    • Language settings

    For more information, see LINE Front-end Framework.

    Try out Messaging API calls in your browser

    We've added a Try button to these sections of the Messaging API reference documentation:

    Clicking Try reveals a form that enables you to test the API call right then and there. You'll need to enter some required information, such as your channel access token (found in the console). Depending on the call, there are also other fields to fill in.

    For now, this feature is only enabled for a small number of operations. We plan to increase the number in future releases to cover more Messaging API functionality.
