Stream Coinbase Advanced Trade market data (ticker, level2, market_trades, candles) and authenticated user channels with HMAC/JWT signing.
빠른 답변: TsgcWSAPI_Coinbase는 Delphi 및 C++ Builder 앱을 Coinbase Advanced Trade에 연결하는 sgcWebSockets 컴포넌트예요. HMAC 또는 JWT 인증을 사용해 공개 시장 채널(ticker, level2, market_trades, candles)과 서명된 user 채널을 스트리밍해요.
Coinbase Advanced Trade client — ticker, level2 order book, market_trades, candles, status and the authenticated user channel.
TsgcWSAPI_Coinbase
Windows, macOS, Linux, iOS, Android
Standard / Professional / Enterprise
Pair with a TsgcWebSocketClient, supply API key/secret for signed channels, then subscribe to ticker, level2, market_trades or user.
uses
sgcWebSocket, sgcWebSocket_API_Coinbase;
var
WSClient: TsgcWebSocketClient;
Coinbase: TsgcWSAPI_Coinbase;
begin
WSClient := TsgcWebSocketClient.Create(nil);
Coinbase := TsgcWSAPI_Coinbase.Create(nil);
Coinbase.Client := WSClient;
Coinbase.Coinbase.ApiKey := 'your-api-key';
Coinbase.Coinbase.ApiSecret := 'your-api-secret';
WSClient.Active := True;

Coinbase.SubscribeUser;
end;// uses: sgcWebSocket, sgcWebSocket_API_Coinbase
TsgcWebSocketClient *WSClient = new TsgcWebSocketClient(this);
TsgcWSAPI_Coinbase *Coinbase = new TsgcWSAPI_Coinbase(this);
Coinbase->Client = WSClient;
WSClient->Active = true;
Coinbase->SubscribeTicker(OPENARRAY(UnicodeString, ("BTC-USD")));
Coinbase->SubscribeLevel2(OPENARRAY(UnicodeString, ("BTC-USD")));Advanced Trade streams: ticker, ticker_batch, level2, market_trades, candles, status, plus the authenticated user channel.
SubscribeTicker, SubscribeTickerBatch, SubscribeLevel2, SubscribeMarketTrades, SubscribeCandles and SubscribeStatus handle every Advanced Trade public stream.
SubscribeUser opens the authenticated user channel and delivers order, fill and account-level events for the signed-in identity.
Coinbase Advanced Trade supports both legacy HMAC signing and newer JWT auth — the component picks the right scheme based on the credentials supplied.
level2 and market_trades deliver a sequence_num per envelope; the component watches for gaps and raises OnException if a re-subscribe is required.
Every subscribe call accepts an array of product IDs (BTC-USD, ETH-USD, ...) so a single connection can multiplex hundreds of instruments.
For snapshot data and order placement use the REST counterpart — the WebSocket component focuses on real-time streams.

Delphi 및 C++ Builder용 Coinbase API 컴포넌트에 대해 자주 묻는 질문이에요.
TsgcWebSocketClient와 TsgcWSAPI_Coinbase 컴포넌트를 추가하고, API 컴포넌트의 Client 속성에 클라이언트를 할당하고, user 채널이 필요하면 Coinbase.ApiKey와 Coinbase.ApiSecret을 설정한 다음 WSClient.Active := True로 설정하고 SubscribeTicker나 SubscribeLevel2 같은 구독 메서드를 호출하세요.TsgcWSAPI_Coinbase 컴포넌트는 Coinbase Advanced Trade WebSocket API에 중점을 둬요. 공개 채널(ticker, ticker_batch, level2, market_trades, candles, status)과 인증된 user 채널을 다뤄요. 스냅샷 데이터와 주문 생성에는 REST 대응 항목을 사용하고, WebSocket 컴포넌트는 실시간 스트림을 처리해요.
