Send LINE Message (universal)
line_send_messageSend text, templates, flex, stickers, coupons, images, or videos to any target—individual, audience, or everyone—while auto-selecting the LINE API and enforcing validation and quota safeguards.
Instructions
Universal LINE sender. Auto-picks the API (reply/push/multicast/narrowcast/broadcast) from the target shape; message shape selects text/template/flex/sticker/coupon/image/video. Feed pre-built objects from line_design_imagemap/line_design_card/line_design_flex via message.message_json; native coupons from line_manage_coupon via message.coupon_id; images hosted by line_prepare_image via message.image.prepared_key (no URLs needed).
mode: send_now (default) sends immediately; draft returns a LINE OA Manager handoff package (URL + Flex JSON + steps) — use when the user wants to SCHEDULE, since the Messaging API can't schedule but the OA Manager UI can; dry_run validates + estimates cost without sending.
Safety: pre-flight /validate before spending quota; Quota Guardian blocks if projected cost >95% of remaining quota unless confirm=true; broadcast { everyone:true } requires confirm=true; quiet-hours 22:00–08:00 BKK warns unless force=true; quiet_push silences the recipient device; reply tokens expire ~1 min (falls back to a push hint).
Returns send_now → { success, transport, request_id?, recipient_count_estimated, quota, warnings[] }; draft and dry_run return their own shapes. Narrowcast needs ~24h before line_get_message_stats shows engagement.
Example: "ส่งโปรให้ผู้หญิง 25-44 กรุงเทพ" → target.filter { genders:["female"], ages:["age_25","age_30"], areas:["bangkok"] }.
