Feishu Send Message as App

Send a Feishu IM message as the app (bot identity). Use when you need to send a message that appears to come from the bot/app, not the user. Uses App Access Token (no user auth needed). Supports text, image, post, card, and other Feishu msg types.

Send a Feishu IM message with app/bot identity — not user identity.

Usage

bash <skill-dir>/scripts/send-message.sh <receive_id> <msg_type> <content> [open_id|chat_id]

Examples

# Text message
bash <skill-dir>/scripts/send-message.sh ou_xxx text "Hello"
