What is SignalLink?
SignalLink is a specialized utility designed for the Openclaw Skills ecosystem, serving as a dedicated router for financial and system alerts. It acts as a bridge between webhook-emitting platforms—such as TradingView, uptime monitors, or CI/CD pipelines—and Telegram, ensuring that critical data reaches the user as a clean, formatted message instantly. By deploying SignalLink as part of your Openclaw Skills library, you eliminate the need for third-party subscription services and maintain full sovereignty over your notification data.
The tool is built on FastAPI for high performance and includes robust security features like constant-time secret validation. It is particularly effective for traders who need low-latency execution signals delivered to their mobile devices without relying on middlemen. Integrating SignalLink into your workflow through Openclaw Skills provides a professional-grade notification system that is both cost-effective and highly customizable.
SignalLink Use Cases
- Forwarding TradingView price alerts and strategy execution signals to a private Telegram group.
- Routing system events, such as uptime monitors or deployment notifications, to a mobile bot.
- Building a self-hosted trading signal system that replaces paid SaaS alternatives.
- Consolidating multiple webhook sources into a single, human-readable Telegram feed using Openclaw Skills.
How SignalLink Works
- The SignalLink server listens for incoming POST requests from external webhook sources on a dedicated endpoint.
- Upon receiving a request, the system validates the X-Webhook-Secret header to ensure the source is authorized.
- The internal logic parses the JSON payload, automatically identifying fields like symbol, action, price, and timeframe.
- A formatting engine converts the raw data into a structured Markdown message with relevant emojis for quick visual scanning.
- The Telegram Bot API client transmits the final message to the user's specific Chat ID immediately.
SignalLink Setup
1. Telegram Configuration
Generate a bot token via @BotFather and retrieve your Chat ID using @userinfobot.
2. Environment Setup
Configure your environment variables by copying the example file provided in the Openclaw Skills repository:
cp .env.example .env
Edit the .env file to include your TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID, and a secure WEBHOOK_SECRET.
3. Deployment
Run the service using Docker for a containerized environment:
docker compose up -d
Alternatively, install dependencies and run via Python:
pip install -r requirements.txt
python -m App.main
SignalLink Data Schema & Taxonomy
SignalLink organizes incoming data using a flexible mapping system. Standard payloads are expected in JSON format with the following primary fields:
| Field | Aliases | Description |
|---|---|---|
| action | signal | The trade direction: buy, sell, close, or neutral |
| symbol | ticker | The asset pair, e.g., BTCUSD or XAUUSD |
| price | close | The execution or trigger price |
| strategy | strategy_name | The name of the alert source or algorithm |
| sl / tp | stop_loss / take_profit | Risk management levels |
The skill also includes a /webhook/raw endpoint for generic key-value pairs that do not follow the standard trading schema.
SignalLink Advanced Features
- Auto-detection of signal formats to handle varying payload structures from different vendors.
- Secure authentication using constant-time comparison to protect against timing-based security threats.
- Multi-format support including raw key-value mapping for non-trading alerts within Openclaw Skills.
- Health check endpoints to facilitate integration with automated monitoring and self-healing infrastructure.
