Skill Overview

Automatically send text and image messages to WeChat groups via API endpoints. Supports single-group or multi-group batch broadcasting, suitable for scenarios such as daily news distribution, content synchronization, and group chat notifications.

Use Cases

1. Morning Briefs and Content Push

Daily morning briefs, trending news, and article summaries are automatically pushed to target WeChat groups, replacing manual copy-paste and improving content distribution efficiency.

2. Group Notifications and Management

Send group announcements, event notifications, and group recaps to multiple WeChat groups to achieve cross-group message synchronization—ideal for community operations and internal enterprise notifications.

3. Bulk Group Messaging

Send one message to multiple WeChat groups at the same time. Supports text + image combinations, suitable for batch outreach needs of content creators, operators, and enterprise users.

Core Features

Sending Text and Image Messages

Supports sending pure text, pure images, or text-and-image combined messages. Images must be base64-encoded and prefixed with a data URI. Supports JPEG/PNG formats. Up to about 10MB of the original image can be sent directly without compression.

Multi-Group Batch Push

Supports sending the same message sequentially to multiple WeChat groups. Each batch processes up to 5 groups; if more than 5, it automatically splits into multiple batches. Failure of a single group does not stop the overall sending; after completion, it summarizes success/failure status.

API Environment Variable Configuration

Configure the endpoint and key via the WECHAT_BOT_HOST and WECHAT_BOT_API_KEY environment variables. The system automatically adds the HTTP prefix if needed, and performs sending only after verifying the configuration is correct.

Common Questions

What types of messages does send-wechat-group-message support?

It supports text messages and image messages, which can be sent separately or combined. Text supports line breaks (use \n). Images must be base64-encoded and include the data:image/<type>;base64, prefix.

Can I send messages to multiple WeChat groups at the same time?

Yes. It supports batch sending to multiple WeChat groups. The system calls the API for each group sequentially. Each batch handles up to 5 groups; if more than 5, it automatically splits into multiple batches. A failure in one group does not affect others, and a final summary report is produced.

Will Chinese messages appear as garbled text?

No. When building the JSON request body with Python, be sure to set ensure_ascii=False so Chinese characters are saved normally instead of being escaped into \uXXXX sequences. Do not use jq --arg + shell variable concatenation to compose Chinese content.

Are there any image format requirements?

Images must be base64-encoded and include the full data URI prefix (e.g., data:image/jpeg;base64,). Supports JPEG/PNG formats with a maximum size of about 10MB. Note that file extensions may not match the actual format. It’s recommended to use the file command to confirm the real format before choosing the corresponding MIME type.
