This is Huobi Java SDK v3, you can import to your project and use this SDK to query all market data, trading and manage your account. The SDK supports RESTful API invoking, and subscribing the market, account and order update from the WebSocket connection.
If you already use SDK v1 or v2, it is strongly suggested migrate to v3 as we refactor the implementation to make it simpler and easy to maintain. The SDK v3 is completely consistent with the API documentation of the new HTX open platform. Compared to SDK versions v1 and v2, due to changes in parameters of many interfaces, in order to match the latest interface parameter situation, v3 version has made adjustments to parameters of more than 80 interfaces to ensure that requests can be correctly initiated and accurate response data can be obtained. Meanwhile, the v3 version has added over 130 new interfaces available for use, greatly expanding the number of available interfaces. We will stop the maintenance of v2 in the near future. Please refer to the instruction on how to migrate v1 or v2 to v3 in section Migrate from v1 or v2
The SDK is compiled by Java8, you can import the source code in java IDE (idea or eclipse)
The example code are in folder /java/src/test/java/com/huobi/examples that you can run directly
If you want to create your own application, you can follow below steps:
- Create the client instance.
- Call the interfaces provided by client.
// Create GenericClient instance and get the timestampGenericClientgenericService = GenericClient.create(HuobiOptions.builder().build());
LongserverTime = genericService.getTimestamp();
System.out.println("server time:" + serverTime);
// Create MarketClient instance and get btcusdt latest 1-min candlestickMarketClientmarketClient = MarketClient.create(newHuobiOptions());
List<Candlestick> list = marketClient.getCandlestick(CandlestickRequest.builder()
.symbol("btcusdt")
.interval(CandlestickIntervalEnum.MIN1)
.size(10)
.build());
list.forEach(candlestick -> {
System.out.println(candlestick.toString());
});This is the folder and package structure of SDK source code and the description
- src/main/java/com/huobi: The core of the SDK
- client: The client that are responsible to access data, this is the external interface layer
- constant: The enum and constant definition
- exception: The exception definition
- model: The data model for response
- service: The internal implementation for each client
- utils: The utilities that include signature, websocket management etc
- src/test/java/com/huobi: The test of the SDK
- examples: The examples how to use client instance to access API and read response
- service: The unit test for service package
- test: The additional test such as performance test
- utils: The unit test for utils package
This SDK provides examples that under src/test/java/com/huobi/example folder, if you want to run the examples to access private data, you need below additional steps:
- Create an API Key first from Huobi official website
- Assign your API access key and secret key to "Constant.java" as below:
publicstaticfinalStringAPI_KEY = "hrf5gdfghe-e74bebd8-2f4a33bc-e7963"publicstaticfinalStringSECRET_KEY = "fecbaab2-35befe7e-2ea695e8-67e56"If you don't need to access private data, you can ignore the API key.
Regarding the difference between public data and private data you can find details in Client section below.
In this SDK, the client is the class to access the Huobi API. In order to isolate the private data with public data, and isolated different kind of data, the client category is designated to match the API category.
All the client is listed in below table. Each client is very small and simple, it is only responsible to operate its related data, you can pick up multiple clients to create your own application based on your business.
| Data Category | Client | Privacy | API Protocol |
|---|---|---|---|
| Generic | GenericClient | Public | Rest |
| Market | MarketClient | Public | Rest, WebSocket |
| Account | AccountClient | Private | Rest, WebSocket v2 |
| Wallet | WalletClient | Private | Rest |
| Sub user | SubUserClient | Private | Rest |
| Trade | TradeClient | Private | Rest |
| Algo | AlgoClient | Private | Rest |
| Isolated margin | IsolatedMarginClient | Private | Rest |
| Cross margin | CrossMarginClient | Private | Rest |
There are two types of privacy that is correspondent with privacy of API:
Public client: It invokes public API to get public data (Generic data and Market data), therefore you can create a new instance without applying an API Key.
// Create a GenericClient instanceGenericClientgenericService = GenericClient.create(newHuobiOptions());
// Create a MarketClient instanceMarketClientmarketClient = MarketClient.create(newHuobiOptions());Private client: It invokes private API to access private data, you need to follow the API document to apply an API Key first, and pass the API Key to the init function
// Create an AccountClient instance with APIKeyAccountClientaccountService = AccountClient.create(HuobiOptions.builder()
.apiKey(Constants.API_KEY)
.secretKey(Constants.SECRET_KEY)
.build());
// Create a TradeClient instance with API KeyTradeClienttradeService = TradeClient.create(HuobiOptions.builder()
.apiKey(Constants.API_KEY)
.secretKey(Constants.SECRET_KEY)
.build());The API key is used for authentication. If the authentication cannot pass, the invoking of private interface will fail.
There are two protocols of API, Rest and WebSocket
Rest: It invokes Rest API and get once-off response, it has two basic types of method: GET and POST
WebSocket: It establishes WebSocket connection with server and data will be pushed from server actively. There are two types of method for WebSocket client:
- Request method: The method name starts with "req-", it will receive the once-off data after sending the request.
- Subscription: The method name starts with "sub-", it will receive update after sending the subscription.
The major difference between v1 and v2 is that the client category.
In SDK v1, the client is categorized as two protocol, request client and subscription client. For example, for Rest API, you can operate everything in request client. It is simple to choose which client you use, however, when you have a client instance, you will have dozens of method, and it is not easy to choose the proper method.
The thing is different in SDK v2, the client class is categorized as seven data categories, so that the responsibility for each client is clear. For example, if you only need to access market data, you can use MarketClient without applying API Key, and all the market data can be retrieved from MarketClient. If you want to operate your order, then you know you should use TradeClient and all the order related methods are there. Since the category is exactly same as the API document, so it is easy to find the relationship between API and SDK. In SDK v2, each client is smaller and simpler, which means it is easier to maintain and less bugs.
Compared to SDK versions v1 and v2, due to changes and updates in the out and in parameters of many interfaces, in order to match the latest interface in and out parameter situation, v3 version has made adjustments and updates to the out and in parameters of more than 80 interfaces to ensure that requests can be correctly initiated and accurate response data can be obtained. Meanwhile, the v3 version has added over 130 new interfaces available for use, greatly expanding the number of available interfaces.
You don't need to change your business logic, what you need is to find the v1 or v2 request client and subscription client, and replace with the proper v3 client. The additional cost is that you need to have additional initialization for each v3 client.
