    New article on converting an MID to a user ID

    New properties for template messages and postback actions released

    Default actions can now be set for template messages

    LINE API Expert is a program that recognizes skilled engineers who have a deep understanding of the APIs provided by LINE and are influential in the community by giving them the title of "LINE API experts". In addition to providing an array of benefits, LINE will also support the various activities of these LINE API experts through this program.

    The LINE API expert program was introduced at the LINE DEVELOPER DAY, September last year and a lot of engineers have applied through the LINE Developers site. Our internal review committee reviewed each item with a strict standard and came up with the final result. Please check the detail on the Expert List page or LINE Engineering Blog.

    We look forward to see the selected members to actively engage in the developer community through meetups, online forum, SNS or blogs, and other means. LINE will be opened to the range of activities and will support their moves with all means.

    For the Q1, a total of 22 qualified engineers have been selected from four Asia countries, including Japan.
