Line-bot

Send a push message to a LINE user, group, or room. Supports all message types: text, image, video, audio, file, location, sticker, template, flex, and imagemap. Example text message: {"type":"text","text":"Hello"}. Example flex: {"type":"flex","altText":"...","contents":{...}}.

Reply to a webhook event using a reply token. The token expires quickly, so use immediately after receiving an event. Free (does not consume message quota).

Validate message objects before sending. Returns 200 OK if valid, or error details if invalid. Use to check message format before push/reply/multicast/broadcast.
