Feishu Send Image#

Send local image files as native Feishu image messages via the Feishu Bot API.

Why This Skill Exists#

OpenClaw's message tool with filePath, media, or buffer parameters only sends file attachments in Feishu, not inline images. This skill calls the Feishu API directly to send proper image messages.

Quick Usage#

Run the script:

bash

bash scripts/feishu_send_image.sh <image_path> <receive_id> <app_id> <app_secret> [receive_id_type]

Arguments#

ArgDescriptionimage_pathLocal path to image (png/jpg/gif/webp)receive_idFeishu open_id (user) or chat_id (group)app_idFeishu app ID from ~/.openclaw/openclaw.json → feishu.accounts.default.appId``app_secretFeishu app secret from ~/.openclaw/openclaw.json → feishu.accounts.default.appSecret``receive_id_type``open_id (default) or chat_id

Example#

bash

bash scripts/feishu_send_image.sh /tmp/chart.png \

Getting Credentials#

Read ~/.openclaw/openclaw.json and extract:

• channels.feishu.accounts.default.appId
• channels.feishu.accounts.default.appSecret

The receiver's open_id comes from inbound message metadata ( sender_id).

How It Works#

1. Get token — POST /auth/v3/tenant_access_token/internal with appId/appSecret
2. Upload image — POST /im/v1/images with image_type=message, returns image_key
3. Send message — POST /im/v1/messages with msg_type=image and the image_key

Output#

On success: OK: image_key=<key> message_id=<id> On failure: prints error and exits with code 1.
