Agent WeChatBot

A TypeScript CLI tool that enables AI agents and humans to send messages through WeChat Official Account API. Designed for customer engagement, template notifications, and CI/CD integrations using App ID + App Secret authentication.

Key Concepts

Before diving in, a few things about WeChat Official Account API:

• Send-only — The Official Account API delivers inbound messages via webhooks only. This CLI cannot list or read received messages.
• Customer service messages — You can send free-form text, image, and news (article) messages to users who have interacted with your account within the last 48 hours.
• Template messages — Pre-approved message templates can be sent at any time. Templates must be created and approved in the WeChat Official Account admin panel.
• App ID — Your Official Account's unique application identifier. Found in the WeChat Official Account admin panel under Development > Basic Configuration.
• App Secret — Your application's secret key, paired with the App ID. Found in the same location.
• OpenID — Each follower has a unique OpenID scoped to your Official Account. Use user list to retrieve follower OpenIDs.
• IP Whitelist — Your server IP must be added to the Official Account's IP whitelist, or API calls will fail with error 40164.
• Rate limits — WeChat enforces API call frequency limits. Customer service messages are limited per account per day.

Quick Start

# Set your API credentials
agent-wechatbot auth set your-app-id your-app-secret

# Verify authentication
agent-wechatbot auth status

# Send a text message (recipient must have interacted within 48h)
agent-wechatbot message send oXXXXXXXXXXXXXXX "Hello from the CLI!"

# List available templates
agent-wechatbot template list --pretty

# List followers
agent-wechatbot user list --pretty

Authentication

API Credential Setup

agent-wechatbot uses App ID + App Secret pairs from the WeChat Official Account admin panel:

# Set credentials (validates against WeChat API before saving)
agent-wechatbot auth set your-app-id your-app-secret

# Check auth status
agent-wechatbot auth status

# Clear stored credentials
agent-wechatbot auth clear

Multi-Account Management

# List stored accounts
agent-wechatbot auth list

# Switch active account
agent-wechatbot auth use <account-id>

# Remove a stored account
agent-wechatbot auth remove <account-id>

Memory

The agent maintains a ~/.config/agent-messenger/MEMORY.md file as persistent memory across sessions. This is agent-managed, the CLI does not read or write this file. Use the Read and Write tools to manage your memory file.

Reading Memory

At the start of every task, read ~/.config/agent-messenger/MEMORY.md using the Read tool to load any previously discovered account IDs, template names, follower OpenIDs, and preferences.

• If the file doesn't exist yet, that's fine. Proceed without it and create it when you first have useful information to store.
• If the file can't be read (permissions, missing directory), proceed without memory. Don't error out.

Writing Memory

After discovering useful information, update ~/.config/agent-messenger/MEMORY.md using the Write tool. Write triggers include:

• After discovering account IDs and App IDs (from auth list, auth status, etc.)
• After discovering template names and their parameters (from template list, etc.)
• After discovering follower OpenIDs (from user list, user get, etc.)
• After the user gives you an alias or preference ("call this the notifications account", "my main template is X")

When writing, include the complete file content. The Write tool overwrites the entire file.

What to Store

• Account IDs (App IDs) with names
• Template IDs with their required parameters
• Frequently used follower OpenIDs with context
• User-given aliases ("notifications account", "marketing account")
• Any user preference expressed during interaction

What NOT to Store

Never store App Secrets or any credentials. Never store full message content (just context). Never store personal user data.

Handling Stale Data

If a memorized template returns an error (template not found, account invalid), remove it from MEMORY.md. Don't blindly trust memorized data. Verify when something seems off. Prefer re-listing over using a memorized value that might be stale.

Format / Example

# Agent Messenger Memory

## WeChat Accounts

- `wx1234567890` - Acme Notifications

## Templates (Acme Notifications)

- `TM00001` - Order confirmation, params: [order_id, customer_name]
- `TM00002` - Shipping update, params: [tracking_number]

## Frequent Recipients

- `oABCD1234` - Test user (internal QA)
- `oEFGH5678` - VIP customer

## Aliases

- "notifications" -> `wx1234567890` (Acme Notifications)

## Notes

- IP whitelist configured for 203.0.113.10
- Customer service messages limited to 48h interaction window

Memory lets you skip repeated template list calls. When you already know a template ID from a previous session, use it directly.

Common Patterns

See references/common-patterns.md for additional workflows.

Send a customer service message within 48h window

Customer service messages can be sent to users who have interacted with your account within the last 48 hours:

# Send a text reply
agent-wechatbot message send oABCD1234 "Thanks for reaching out! We'll look into this right away."

# Send a news article
agent-wechatbot message send-news oABCD1234 \
  --title "Your Order Update" \
  --description "Your order #12345 has been shipped" \
  --url "https://example.com/orders/12345" \
  --picurl "https://example.com/images/shipping.jpg"

Send a template notification (anytime)

Template messages can be sent at any time, regardless of the 48h window:

# List templates to find the right one
agent-wechatbot template list --pretty

# Send a template message with data
agent-wechatbot template send oABCD1234 TM00001 \
  --data '{"order_id":{"value":"ORD-9876"},"status":{"value":"Shipped"}}' \
  --url "https://example.com/orders/9876"

List and inspect followers

# Get first page of followers
agent-wechatbot user list --pretty

# Get next page
agent-wechatbot user list --next-openid oLAST_OPENID --pretty

# Get details for a specific follower
agent-wechatbot user get oABCD1234 --pretty

CI/CD deployment notification

agent-wechatbot template send oABCD1234 deployment_alert \
  --data '{"version":{"value":"v2.1.0"},"environment":{"value":"production"},"status":{"value":"success"}}'

Templates

See templates/ directory for runnable examples:

• post-message.sh - Send a customer service message with error handling and retries
• account-summary.sh - Generate account, template, and follower summary
• send-template.sh - Send a template message with parameters

Error Handling

All commands return consistent error format:

{
  "error": "No credentials. Run \"auth set <app-id> <app-secret>\" first."
}

Common errors: No credentials, Account not found, Invalid credentials, WeChat API error (errcode: 40001), IP not in whitelist (errcode: 40164), Rate limit exceeded (errcode: 45009).

Configuration

Credentials stored in ~/.config/agent-messenger/wechatbot-credentials.json (0600 permissions).

Config format:

{
  "current": { "account_id": "wx1234567890" },
  "accounts": {
    "wx1234567890": {
      "app_id": "wx1234567890",
      "app_secret": "...",
      "account_name": "wx1234567890"
    }
  }
}

Limitations

• Cannot list or read received messages — WeChat Official Account API delivers inbound messages via webhooks only. This CLI is send-only.
• Customer service messages require 48h window — Free-form text, image, and news messages only work within 48 hours of the user's last interaction.
• Template messages require pre-approval — Templates must be created and approved in the WeChat admin panel before use.
• IP whitelist required — Your server's IP must be added to the Official Account's whitelist, or you'll get error 40164.
• Media IDs required for images — Images must be uploaded to WeChat's media platform first. The CLI accepts media IDs, not URLs.
• No group chat support — Official Account API communicates with individual followers only.
• No real-time events / WebSocket connection — Inbound messages require a separate webhook server.
• No message editing or deletion
• No voice or video calls
• Access tokens expire — Tokens are valid for 7200 seconds. The CLI handles automatic refresh.

Troubleshooting

agent-wechatbot: command not found

agent-wechatbot is NOT the npm package name. The npm package is agent-messenger.

If the package is installed globally, use agent-wechatbot directly:

agent-wechatbot message send oABCD1234 "Hello"

If the package is NOT installed, run it directly with npx -y:

npx -y agent-messenger wechatbot message send oABCD1234 "Hello"

Note: If the user prefers a different package runner (e.g., bunx, pnpx, pnpm dlx), use that instead.

NEVER run npx agent-wechatbot, bunx agent-wechatbot, or pnpm dlx agent-wechatbot. It will fail or install a wrong package since agent-wechatbot is not the npm package name.

How to get API credentials

1. Log in to the WeChat Official Account admin panel
2. Navigate to Development > Basic Configuration
3. Copy your App ID and App Secret (you may need to reset the secret if you don't have it saved)
4. Add your server's IP to the IP Whitelist
5. Run agent-wechatbot auth set <app-id> <app-secret>

IP whitelist errors (40164)

If you get error 40164, your server's IP is not in the Official Account's whitelist. Add it in the admin panel under Development > Basic Configuration > IP Whitelist.

Token errors (40001, 42001)

These indicate an expired or invalid access token. The CLI handles automatic token refresh, but if you see persistent errors:

• Verify your App Secret hasn't been reset in the admin panel
• Re-run agent-wechatbot auth set <app-id> <app-secret> with the current credentials

Rate limiting (45009)

WeChat enforces API call frequency limits. If you hit error 45009, wait before retrying. For bulk operations, add delays between requests.
