    Rich menu features for Messaging API released

    We've released rich menu features for the Messaging API which lets you display different rich menus to different users. By using the newly released rich menu endpoints, you can create, link, and manage your rich menus programmatically via the API instead of using LINE@ Manager. The rich menu endpoints provide greater freedom in designing rich menus and the ability to set postback actions to specified areas.

    In addition to the current rich menu size of 2500x1686 on LINE@ Manager, you can now create smaller rich menus that are 2500x843 with the Messaging API. This smaller rich menu size lets you display more of the chat screen while still providing an interactive menu for the user.

    Both rich menus created using LINE@ Manager and the Messaging API are supported and can be used at the same time.

    Note: These rich menu features are only supported on LINE 7.14.0 and later for Android and iOS.

    For more information on how to use the new rich menu features, see the following pages.
