LINE Messaging API
The core LINE bot API — 73 operations for replying, pushing, multicasting, broadcasting and narrowcasting messages to LINE users, plus rich menus, Flex messages, group and room membership, profiles, followers, message quota, delivery statistics, coupons, memberships and webhook endpoint configuration. Supports idempotent retries via the X-Line-Retry-Key header on the four metered send operations. Binary content (message media, rich menu images) is served from api-data.line.me rather than api.line.me.
