    New Messaging API endpoint for sending narrowcast messages

    An endpoint for sending narrowcast messages has been added to the Messaging API.

    This endpoint lets you send push messages to multiple users at any time.

    You can specify the recipient using certain attributes (gender, age, OS type, region etc) and retargeting (audience).

    For more information, see Send messages to multiple users using attribute information and retargeting.

    Documentation available in Japanese only. English coming soon.

    Update your code that uses the suspended LIFF SDK API

    As announced on November 29, 2019, these APIs on LINE v9.19.0 and later for iOS were temporarily suspended due to technical issues.

    • liff.scanCode()
    • liff.bluetooth.*

    Starting today, for end users using the LIFF app on LINE v9.19.0 and later for iOS, each API works as follows.

    API Function
    liff.scanCode() API is undefined
    liff.bluetooth.* If the Bluetooth plug-in fails to initialize when calling liff.initPlugins(['bluetooth']), a FORBIDDEN error is returned.

    If you use liff.scanCode(), we recommend that you also consider the above case and verify that the function exists.

    Before modification:

    liff.scanCode().then(result => {
      // result = { value: '' }


    if (liff.scanCode) {
        liff.scanCode().then(result => {
          // result = { value: '' }

    For more information, see LIFF v2 API reference.

    LINE will continue to improve the quality of its services. Thank you for your understanding.
