·

Introduction to go-okx

go-okx is a powerful Golang SDK designed to seamlessly interact with OKX's V5 API. This open-source library simplifies cryptocurrency trading, account management, and market data access through well-structured REST and WebSocket interfaces.

Key Features

Installation Guide

To install the go-okx package, run:

go get github.com/iaping/go-okx

This command fetches the latest stable version of the SDK and adds it to your Go workspace.

REST API Implementation

Here's how to authenticate and make REST API calls:

package main

import (
  "log"
  "github.com/iaping/go-okx/rest"
  "github.com/iaping/go-okx/rest/api/account"
)

func main() {
  auth := common.NewAuth("your_api_key", "your_secret_key", "your_passphrase", false)
  client := rest.New("", auth, nil)
  
  param := &account.GetBalanceParam{}
  req, resp := account.NewGetBalance(param)
  
  if err := client.Do(req, resp); err != nil {
    panic(err)
  }
  log.Println(req, resp.(*account.GetBalanceResponse))
}

WebSocket Connections

Public WebSocket Example

package main

import (
  "log"
  "github.com/iaping/go-okx/ws/public"
)

func main() {
  tickerHandler := func(c public.EventTickers) {
    log.Println(c)
  }
  
  errorHandler := func(err error) {
    panic(err)
  }
  
  if err := public.SubscribeTickers("BTC-USDT", tickerHandler, errorHandler, false); err != nil {
    panic(err)
  }
  
  select {}
}

Private WebSocket Example

package main

import (
  "log"
  "github.com/iaping/go-okx/common"
  "github.com/iaping/go-okx/ws"
  "github.com/iaping/go-okx/ws/private"
)

func main() {
  auth := common.NewAuth("your_api_key", "your_secret_key", "your_passphrase", false)
  
  args := &ws.Args{
    InstType: "SPOT",
  }
  
  orderHandler := func(c private.EventOrders) {
    log.Println(c)
  }
  
  errorHandler := func(err error) {
    panic(err)
  }
  
  if err := private.SubscribeOrders(args, auth, orderHandler, errorHandler); err != nil {
    panic(err)
  }
  
  select {}
}

Best Practices

  1. Error Handling: Always implement robust error handling
  2. Rate Limiting: Respect OKX's API rate limits
  3. Security: Store API keys securely
  4. Testing: Thoroughly test in sandbox environment first
