Here is a sample of how to create order
Java
OkHttpClient client = new OkHttpClient().newBuilder()
  .build();
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "{\"symbol\":\"BTCUSDT\",\"volume\":1,\"side\":\"BUY\",\"type\":\"LIMIT\",\"price\":10000,\"newClientOrderId\":\"\",\"recvWindow\":5000}");
Request request = new Request.Builder()
  .url("https://openapi.xxx.com")
  .method("POST", body)
  .addHeader("X-CH-APIKEY", "Your API key")
  .addHeader("X-CH-TS", "1596543296058")
  .addHeader("Content-Type", "application/json")
  .addHeader("X-CH-SIGN", "encrypt sign")
  .build();
Response response = client.newCall(request).execute();
Go
package main
​
import (
  "fmt"
  "strings"
  "net/http"
  "io/ioutil"
)
​
func main() {
​
  url := "https://openapi.xxx.com"
  method := "POST"
​
  payload := strings.NewReader("{\"symbol\":\"BTCUSDT\",\"volume\":1,\"side\":\"BUY\",\"type\":\"LIMIT\",\"price\":10000,\"newClientOrderId\":\"\",\"recvWindow\":5000}")
​
  client := &http.Client {
  }
  req, err := http.NewRequest(method, url, payload)
​
  if err != nil {
    fmt.Println(err)
  }
  req.Header.Add("X-CH-APIKEY", "Your API key")
  req.Header.Add("X-CH-TS", "1596543881257")
  req.Header.Add("Content-Type", "application/json")
  req.Header.Add("X-CH-SIGN", "encrypt sign")
​
  res, err := client.Do(req)
  defer res.Body.Close()
  body, err := ioutil.ReadAll(res.Body)
​
  fmt.Println(string(body))
}
Python
import requests
​
url = "https://openapi.xxx.com"
​
payload = "{\"symbol\":\"BTCUSDT\",\"volume\":1,\"side\":\"BUY\",\"type\":\"LIMIT\",\"price\":10000,\"newClientOrderId\":\"\",\"recvWindow\":5000}"
headers = {
  'X-CH-APIKEY': 'Your API key',
  'X-CH-TS': '1596543881257',
  'Content-Type': 'application/json',
  'X-CH-SIGN': 'encrypt sign'
}
​
response = requests.request("POST", url, headers=headers, data = payload)
​
print(response.text.encode('utf8'))

Php
<?php
require_once 'HTTP/Request2.php';
$request = new HTTP_Request2();
$request->setUrl('https://openapi.xxx.com');
$request->setMethod(HTTP_Request2::METHOD_POST);
$request->setConfig(array(

try {
  $response = $request->send();
  if ($response->getStatus() == 200) {
    echo $response->getBody();
  }
  else {
    echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
    $response->getReasonPhrase();
  }

NodeJs
