Usage

API usage

// Initialize Kiteconnect using apiKey.
KiteConnect kiteSdk = new KiteConnect("your_apiKey");

// Set userId.
kiteSdk.setUserId("your_userId");

/* First you should get request_token, public_token using kitconnect login and then use request_token, public_token, api_secret to make any kiteconnect api call.
Get login url. Use this url in webview to login user, after authenticating user you will get requestToken. Use the same to get accessToken. */
String url = kiteSdk.getLoginUrl();

// Get accessToken as follows,
User user =  kiteSdk.requestAccessToken("request_token", "your_apiSecret");

// Set request token and public token which are obtained from login process.
kiteSdk.setAccessToken(userModel.accessToken);
kiteSdk.setPublicToken(userModel.publicToken);

// Set session expiry callback.
kiteSdk.setSessionExpiryHook(new SessionExpiryHook() {
    @Override
    public void sessionExpired() {
        System.out.println("session expired");                    
    }
});

// Get margins returns margin model, you can pass equity or commodity as arguments to get margins of respective segments.
Margin margins = kiteSdk.getMargins("equity");
System.out.println(margins.available.cash);
System.out.println(margins.utilised.debits);

/** Place order method requires a orderParams argument which contains,
   * tradingsymbol, exchange, transaction_type, order_type, quantity, product, price, trigger_price, disclosed_quantity, validity
   * squareoff_value, stoploss_value, trailing_stoploss
   * and variety (value can be regular, bo, co, amo)
   * place order will return order model which will have only orderId in the order model
   * Following is an example param for LIMIT order,
   * if a call fails then KiteException will have error message in it
   * Success of this call implies only order has been placed successfully, not order execution. */

   OrderParams orderParams = new OrderParams();
   orderParams.quantity = 1;
   orderParams.orderType = Constants.ORDER_TYPE_LIMIT;
   orderParams.tradingsymbol = "ASHOKLEY";
   orderParams.product = Constants.PRODUCT_CNC;
   orderParams.exchange = Constants.EXCHANGE_NSE;
   orderParams.transactionType = Constants.TRANSACTION_TYPE_BUY;
   orderParams.validity = Constants.VALIDITY_DAY;
   orderParams.price = 122.2;
   orderParams.triggerPrice = 0.0;
   orderParams.tag = "myTag"; //tag is optional and it cannot be more than 8 characters and only alphanumeric is allowed

   Order order = kiteConnect.placeOrder(orderParams, Constants.VARIETY_REGULAR);
   System.out.println(order.orderId);

WebSocket live streaming data

 /** To get live price use websocket connection.
         * It is recommended to use only one websocket connection at any point of time and make sure you stop connection, once user goes out of app.
         * custom url points to new endpoint which can be used till complete Kite Connect 3 migration is done. */
