General API Information

Professional traders can easily execute their strategies across all crypto-to-crypto and other crypto-fiat pairs. With one deposit and KYC process, traders can reallocate assets among exchanges and start trading.

A legitimate request consists of following parts：

Create API Key You could create API Key under menu API Management on Apifiny web GUI.

avatar

API Key consists of the following two parts.

The Base URLs:

We offer co-location services for the clients, for the venues we offer co-location service, the base URL is different individually, it is recommended to use the special URL of each co-located exchanges regarding the order related requests to reduce the network latency. Make sure to use the right base URL accordingly. We now support 8 exchanges, more will be coming soon.

For the rest venues, use a unified URL. e.g. api.apifiny.com

About Venue:

A “venue” is an target exchange. For example: “BINANCE” is accessed by setting venue parameter to BINANCE: "venue": "BINANCE". Get available "venues" at Apifiny by /listVenueInfo.

Make Request

A request contains: HTTP method (e.g. GET or POST), Base URL, Endpoint(request path, e.g. /account) and Request parameter.

For public requests, such as Market Data, base information, see an example:

RESR API Market Data Request Example:

curl -X GET "https://api.apifiny.com/md/orderbook/v1/BTCUSDT/BINANCE"

For authenticated requests, the following parameter should be sent with the request:

Parameter Description
apiKey Your API key, displayed as the Access key on web GUI
signature Hash value of the request body using HMAC SHA256, see signature
timestamp A timestamp for your request, number of milliseconds since Unix epoch
recvWindow [Optional] An additional parameter, may be sent to specify the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000

Standard response

All requests will have a standard response consisting of the following:

The structure of the response:

{
  "result": null,
  "error": {
    "code": 0x02002B,
    "message": "Account doesn't exist, please verify account ID"
  }
}

After making an API request, the server will send back a response in JSON format. The response includes:

Parameter Description
result when the request is successful, this key will include the result of the request. When the request is not successful, its value is null.
error when the request is not successful, the key will give the error message. Its value is null when the request is successful.
code Error code. Please refer to the error code explanation section.
message Error message.

Authentication

Signature

Signature Generating Method:

// js
signature = CryptoJS.HmacSHA256(request_data, Your_secret_key);

# python3
import hashlib
import hmac
import json

def gen_signature(Your_secret_key, data) -> str:
    message = data.encode("utf-8")
    return hmac.new(Your_secret_key.encode("utf-8"), message, digestmod=hashlib.sha256).hexdigest()

// Java
public String hmacSha256(String secretKey, String body) {
    try {
        Mac mac = Mac.getInstance("HmacSHA256");
        SecretKey secretKeySpec = new SecretKeySpec(secretKey.getBytes(StandardCharsets.UTF_8), "HmacSHA256");
        mac.init(secretKeySpec);
        return Hex.encodeHexString(mac.doFinal(body.getBytes()));
    } catch (Exception e) {
        throw new IllegalArgumentException("Invalid key for hmac initialization.", e);
    }
}

Every private endpoint must be signed, private endpoints are available for order management and account balances.

Here is the detailed examples below:

Example 1:

GET requests example:

# curl command
curl -X GET -H "apiKey: hY***lY" -H "signature: eyJh***heQs" "https://api.apifiny.com/ac/v2/APIFINY/account/queryAccountInfo?accountId=STA-00000001&recvWindow=5000&timestamp=1499827319559"

accountId=STA-00000001

&venue=BINANCE

&recvWindow=500

&recvWindow=5000

&timestamp=1499827319559

Example 2:

POST requests example:

# curl command  
curl -X POST -H "Content-Type: application/json" -H "apiKey: hY***lY" -H "signature: eyJhY***nyheQs" "https://api.apifiny.com/ac/v2/APIFINY/asset/withdraw" \
-d '{"accountId": "STA-00000001","venue":"BINANCE","coin": "USDT.ETH","amount": 100.00,"address": "0x3955fefd67w45p8v","ticket": "b21987ft568ij36f","recvWindow": 5000,"timestamp": 1499827319559}'

{ "accountId": "STA-00000001", "venue": "BINANCE", "coin": "USDT.ETH", "amount": 100.00, "address": "0x3955fefd67w45p8v", "ticket": "b21987ft568ij36f", "recvWindow": 5000, "timestamp": 1499827319559 }

Time security

Networks can be unstable and unreliable, with recvWindow, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server.

Time security, the logic is as follows:

  if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow)
  {
    // process request
  } 
  else 
  {
    // reject request
  }

Time Stamp

If you get the error:"Timestamp for this request is outside of the recvWindow", you can compare the client timestamp with our server clock, or try +/- 1 second. This is the endpoint to query our server time: /currentTimeMillis.

Rate Limits

There are throttling limits for HTTPS requests, referred to as rate limits by Account ID. These are set at 20 requests per second and will result in an error message, “rate limit is exceeded”, if breached.

Sandbox

Sandbox is the test environment, Apifiny sandbox is available for testing API connectivity and web trading.

The sandbox hosts a subset of the connected exchanges and only the BTC/USDT market data, supports most of the functionality except query address. You can claim paper money for testing.

Note that login sessions and API keys are seperate from production. Log into the sandbox web GUI to create an API key, trading, etc.

Sandbox URLs

Use the following URLs to test your API connectivity.

API URL
REST API https://api-sandbox.apifiny.com
Websocket wss://api-sandbox.apifiny.com
FIX API fix-sandbox.apifiny.com:1443

Trading

Introduction

Clients will typically be using the Websocket API to subscribe to the market data and RESTful API to submit orders. Clients can use the websocket API to subscribe to the order updates or use RESTful API to get order updates. A typical trade flow would be as follows:

Step 1: Subscribe to market data. The websocket endpoint used to subscribe and unsubscribe for market data is wss://api.apifiny.com/md/ws/v1 . Request and reply are in JSON format.

The RESTful endpoint is GET https://api.apifiny.com/md/orderbook/v1/{SYMBOL}/{VENUE}, where {SYMBOL} denotes the currency pair of interest and the {VENUE} denotes the exchange.

Step 2: Create order and send order using the RESTful API.

The method for creating an order is order/newOrder, which enables an order to be created and submitted. Note that the orderId is optional, if requested, it should be composed of: account number+random number+13 digit timestamp+3 digit random number. Up to 64 digits.

for example：xxxxxxxxxxxxxx1614254993065992

Step 3: Subscribe to the order updates using websocket /ws/trading, the message is sent to notify the client that the order execution report changed.

A number of methods enable the querying of order(s) state: the URL endpoints are:

/order/queryOrderInfo to find the state of a single submitted order;

/order/listOpenOrder to get a list of all open orders;

/order/listCompletedOrder to get a list of all complete orders;

/order/listFilledOrder to get a list of fills.

Step 4: Cancel Order (as needed). When an order that was submitted and is open needs to be canceled, The URL endpoint is /order/cancelOrder. Any order that has a status of PENDING_SUBMIT or has already been canceled, cannot be canceled. In addition, cancelledUpdatedAt must be null.

Order Type:

Order Type Description
LIMIT Limit Order
MARKET Market Order*
STOP Stop Limit Order* with a pre-set Trigger price and Condition
ICEBERG Iceberg Order, an advanced order type.

*Only 11 exchanges support market order now, they are Binance, Binance(US), Coinbase(pro), Coinbase Pro(UK), Crypto, Exmo, Huobi, Iitbit, Kucoin, OKX, Okcoin, others will be coming soon.

Stop Orders become active and wait to trigger based on the movement of the last trade price.

There are two types of stop orders, ENTRY and LOSS, allow a user to set a Trigger price and Condition: "If price rises to" or "If price drops to" the specified Trigger price.

stop ENTRY: Triggers when the last trade price changes to a value at or above the triggerPrice.

stop LOSS: Triggers when the last trade price changes to a value at or below the triggerPrice.

The last trade price is the last price at which an order was filled. Note that when stop orders are triggered, they execute as limit orders.

Iceberg Order :

average : average size the size you expect the order size showing on the orderbook, the visible amount. (The visible size shall be greater than the minimum order size, or an error will occur.) variance: a variance range, within which the system will generate a random amount of added to or deducted from the visible amount each time placing the order, so the behavior of the algorithm will not be predictable.

Introduction

There is something you should know about the newly introduced smart routing order, they are as follows:

  1. It routes your order for best execution based on the consolidated order book, meaning it will split the order up to send to multiple exchanges for the most optimum execution price.

  2. When you want to make sure your order is completed as soon as possible, you should make sure you have sufficient balances at most liquidated exchanges. Allocate funds to exchange accounts, you can transfer funds to each sub-account using this endpoint: Transfer Funds.

  3. This algorithm can be used for any size. It is suggested that the minimum notional of the SOR order should be over $10 value, otherwise the order might get rejected at most of the exchanges.

  4. Terminate/Cancel a SOR order takes some time to process, because the system needs to clear all the orders that have been sent to the target exchanges before the order can be terminated completely.

  5. Currently, the SOR order will stand for 24hrs, the system would terminate the order when times up no matter how much amount it's been filled.

Websocket API

Apifiny Websocket API can be used to subscribe for a feed of real time data, such as price evolution or market state data. Also updates for orders, trades and account balances.

In addition, the API can allow clients to create and cancel orders by reusing the same established websocket connection.

Connectivity

Heartbeat and Connection

Once the Websocket Client connected to the Websocket Server, the system will send a "SUCCESS" message.

{
    "type": "auth",
    "result": "Websocket connection succeeded",
    "error": null
}

Websocket API supports two-way heartbeat. Both Server and Client can send ping message, which the opposite side can return with pong message. The Client side can send ping messages every pingInterval time to the server to keep alive the link.

Websocket Client sends heartbeat:

{“action”:“heartbeat”,“data”:“ping”}

When the Server receives this heartbeat message, it will respond with a matching "pong" message:

{"type":"heartbeat","result":"pong","error":null}

Connection lifecycle

Market Data

WebSocket endpoint provides real-time market data streaming which works in Subscribe-Publish communication model.

The base endpoint for Market Data is:

wss://api.apifiny.com/md/ws/v1

Subscribe/Unsubscribe to streams

The following data can be sent through the websocket instance in order to subscribe/unsubscribe from streams.

Subscribe to a stream

Request(Subscribe):

{
  "channel":"ChannelName", 
  "symbol":"BTCUSDT",
  "venues":["BINANCE"],
  "action":"sub"
}

Unsubscribe to a stream

Request(Unsubscribe) :

{
  "channel":"ChannelName",
  "symbol":"BTCUSDT",
  "venues":["BINANCE"],
  "action":"unsub"
}

The request for subscribe/unsubscribe must be in JSON format.

# python3
msg = {"channel": "trade", "symbol": 'symbol', "venues": 'VENUES', "action": "sub"}
# msg = {"channel": "symbol": 'BTCUSDT',  "action": "sub"}
def sub_md(message):
    from websocket import create_connection
    import ssl
    sslopt = {"cert_reqs": ssl.CERT_NONE}
    con = create_connection('wss://api.apifiny.com/md/ws/v1', sslopt=sslopt)
    con.send(json.dumps(message))
    while True:
        response = con.recv()
        if 'ping' in response:
            pong = response.replace('ping', 'pong')
            con.send(pong)
        print(response)

FIX API

FIX (Financial Information exchange) is a standard protocol which can be used to enter orders, submit cancel requests, and receive fills. Users of the FIX API will typically have existing software using FIX for order management. Users who are not familiar with FIX should first consider using the REST API.

FIX API can be implemented using QuickFIX with the following language support:

Configuration information are as follows：

Status/Error Codes

There are two categories of error codes, one set generated by HTTP, typically by a server for a client request, and the other category is a set of Apifiny Connect application status/error codes.

HTTP Error code

HTTP status codes are divided into 5 ranges as follows:

Some of the most common HTTP error codes include:

HTTP 403 - too many errors and IP is blocked

HTTP 502 - service is not available

Apifiny Connect Status/Error Codes

Apifiny Connect status/error codes are returned as a hexadecimal number. The number on the farthest right delineates client side errors (designated by the hexadecimal number A) from server side errors (designated by the hexadecimal number B).

Client side errors should be corrected at the client and the request resubmitted. Server side errors will have a max retry count as well as a resubmit interval of 50 ms. Persistent resubmissions will result in suspension of the submitting IP.
