Fixer API with 5 different programming languages

We will integrate the historical exchange rate data service provided by Fixer API into 5 different programming languages. 

Before proceeding with the integration, we select one of the most exclusive and affordable packages of Fixer API and become a member. Then we obtain the API key required to use the Fixer API.

After obtaining the API key, we can look at the integration of Fixer API with different programming languages.


var requestOptions = {
  method: ‘GET’,
  redirect: ‘follow’

fetch(“*****ff&symbols=USD,TRY,CAD”, requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log(‘error’, error));


package main

import (

func main() {

  url := “*****ff&symbols=USD,TRY,CAD”
  method := “GET”

  client := &http.Client {
  req, err := http.NewRequest(method, url, nil)

  if err != nil {
  res, err := client.Do(req)
  if err != nil {
  defer res.Body.Close()

  body, err := ioutil.ReadAll(res.Body)
  if err != nil {


var axios = require(‘axios’);

var config = {
  method: ‘get’,
  url: ‘*****ff&symbols=USD,TRY,CAD’,
  headers: { }

.then(function (response) {
.catch(function (error) {


conn = http.client.HTTPSConnection(“”)
payload = ”
headers = {}
conn.request(“GET”, “/api/2015-09-08?access_key=c0*****ff&symbols=USD,TRY,CAD”, payload, headers)
res = conn.getresponse()
data =


require_once ‘HTTP/Request2.php’;
$request = new HTTP_Request2();
  ‘follow_redirects’ => TRUE
try {
  $response = $request->send();
  if ($response->getStatus() == 200) {
    echo $response->getBody();
  else {
    echo ‘Unexpected HTTP status: ‘ . $response->getStatus() . ‘ ‘ .
catch(HTTP_Request2_Exception $e) {
  echo ‘Error: ‘ . $e->getMessage();

We have implemented the integration of Fixer API with applications very simply and quickly. If the ‘base’ field is not set in the request to the Fixer API, EUR is selected by default. We did not set the ‘base’ field either, and we expect the values ​​of USD, TRY and CAD currencies to correspond to the EUR currency on the date we specified.

When these applications are run, the following output will be printed on the console screen of the applications.

  “success”: true,
  “timestamp”: 1441670399,
  “historical”: true,
  “base”: “EUR”,
  “date”: “2015-09-08”,
  “rates”: {
    “USD”: 1.120599,
    “TRY”: 3.377687,
    “CAD”: 1.481852

module.exports = router;

Now let’s run the application by typing the following command from the terminal.
