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
|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.|
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
- The LIFF URL used to launch LIFF (e.g.: line://app/1234567890-AbcdEfgh) will change.
To avoid confusion, delete the LIFF app added to the Messaging API channel after adding to the LINE Login channel.
