-====== Connecting and Authenticating ======
-To start using the **Plus500 Futures Technologies WebSocket API**, clients must establish a secure WebSocket connection and authenticate before subscribing to data streams or submitting orders.
-===== WebSocket Connection =====
-^ Environment ^ WebSocket URL ^
-| **Live** | `wss://wss.t4login.com/v1` |
-| **Simulator** | `wss://wss-sim.t4login.com/v1` |
-Clients must connect using **WebSocket Secure (WSS) over SSL/TLS** on port **443**. Messages are encoded using **Google Protocol Buffers (Protobuf)**.
-To maintain an active connection, both the client and server must send a **heartbeat message every 20 seconds**. If no other message is sent during that interval, the server will send a heartbeat automatically. If the server does not receive **any message for 3 consecutive heartbeat intervals**, it will terminate the connection.
-===== Authentication =====
-Authentication must be performed **immediately after establishing a connection** by sending a `LoginRequest` message. This API supports two authentication methods:
-- **API Key Authentication** (provide only the `api_key` field).
-- **Username/Password Authentication** (send `firm`, `username`, `password`, `app_name`, and `app_license`).
-**Example LoginRequest (API Key Authentication):**
-<code>
-{
-  "api_key": "abc123-xyz789"
-}
-</code>
-**Example LoginRequest (Username/Password Authentication):**
-<code>
-{
-  "firm": "T4Futures",
-  "username": "trader123",
-  "password": "securepassword",
-  "app_name": "CustomTradingApp",
-  "app_license": "LICENSE-4567"
-}
-</code>
-If authentication succeeds, the server will return a `LoginResponse` with a session ID and assigned roles.
-**Example Successful LoginResponse:**
-<code>
-{
-  "result": "LOGIN_SUCCESS",
-  "session_id": "sess-123456789",
-  "user_id": "user-456",
-  "firm_id": "firm-789",
-  "roles": ["Trader", "RiskManager"]
-}
-</code>
-If authentication fails, the server will return an error message. Some common reasons for failure include:
-^ LoginResult Code ^ Meaning ^
-| `LOGIN_FAILED` | Invalid credentials. |
-| `TWO_FACTOR_REQUIRED` | Two-factor authentication is required. |
-| `UNAUTHORIZED` | API key or username/password is incorrect. |
-| `PASSWORD_EXPIRED` | The password must be changed before logging in. |
-| `LOCKED_OUT` | Too many failed login attempts. |
-For detailed message formats, refer to the [[message_reference|Message Reference]] page.
-===== Reconnection & Session Handling =====
-If the connection is lost, clients should **reconnect automatically** and **re-authenticate** as session resumption is **not supported**. Connections remain valid as long as heartbeats are exchanged.
-The system undergoes **scheduled maintenance every week**, shutting down at **midnight on Friday** and resuming service on **Sunday morning**. During this period, all connections will be dropped.
-===== Next Steps =====
-Once authenticated, clients can:
-  * Subscribe to **market data streams** ([[quote_data|Quote Data]]).
-  * Retrieve **account and position details** ([[account_data|Account Data]]).
-  * Submit **orders and manage trades** ([[order_submission|Order Submission]]).

-💡 **Tip:** Test your WebSocket connection using tools like `wscat` or a sample SDK.
