Feishu Send Image

Send images directly in Feishu chat as native image messages (not file attachments). Use when: need to send a generated image, chart, screenshot, or any local image file to a Feishu user or group chat. Triggers: "发图", "send image", "发送图片", sending charts/graphs/screenshots via Feishu. Note: OpenClaw's built-in message tool (filePath/media/buffer) does NOT work for Feishu image sending — it only produces file attachments. This skill bypasses that limitation by calling Feishu Bot API directly.

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

Arguments

Arg	Description
image_path	Local path to image (png/jpg/gif/webp)
receive_id	Feishu open_id (user) or chat_id (group)
app_id	Feishu app ID from ~/.openclaw/openclaw.json → feishu.accounts.default.appId
app_secret	Feishu app secret from ~/.openclaw/openclaw.json → feishu.accounts.default.appSecret
receive_id_type	open_id (default) or chat_id

Example

bash scripts/feishu_send_image.sh /tmp/chart.png \
  ou_38470740452f6083ce189b7ddec722f8 \
  cli_a92c368412f9dcb1 \

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.
