Accessing the API: Base URLs and Protocols
CoinEx supports two primary communication protocols for accessing its services:
- HTTP/HTTPS for RESTful API interactions
- WebSockets for real-time data streaming (e.g., price updates, order book changes)
All API endpoints are accessible via secure base URLs:
- REST API:
https://api.coinex.com/v2/ - WebSocket:
wss://wss.coinex.com/v2/
These endpoints allow you to retrieve market data, manage accounts, execute trades, and monitor positions across spot and futures markets.
Securing Your Integration: Authentication Mechanism
Security is paramount when interacting with financial systems. The CoinEx API employs a robust authentication system based on API keys and secret keys, ensuring only authorized users can access sensitive account functions.
To get started:
- Generate an API key and secret through the CoinEx API Management Console.
- Assign specific permissions (e.g., read-only balance access or full trading rights).
- Use your secret key to create digital signatures for each private request.
Every private API call must include:
- Your API key
- A timestamp
- A signature generated using HMAC-SHA256 encryption
This ensures request integrity and prevents replay attacks. For detailed implementation examples, refer to the official authorization guide.
