How to use

Basic request:

// Get the ETH/USD ticker via rest request
var restClient = new BitstampRestClient();
var tickerResult = await restClient.ExchangeApi.ExchangeData.GetTickerAsync("ETH/USD");
var lastPrice = tickerResult.Data.LastPrice;

Place order:

var restClient = new BitstampRestClient(opts => {
	opts.ApiCredentials = new BitstampCredentials("APIKEY", "APISECRET");
});

// Place Limit order to go long for 0.1 ETH at 2000
var orderResult = await restClient.ExchangeApi.Trading.PlaceLimitOrderAsync(
    "ETH/USD-PERP",
    OrderSide.Buy,
    2000,
    OrderType.Limit,
    0.1m);

WebSocket subscription:

// Subscribe to ETH/USDT ticker updates via the websocket API
var socketClient = new BitstampSocketClient();
var tickerSubscriptionResult = socketClient.ExchangeApi.SubscribeToTradeUpdatesAsync("ETH/USD", (update) => 
{
  var lastPrice = update.Data.Price;
});

CryptoExchange.Net

Bitstamp.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also allows for easy access to different exchange API's.
