Then, let’s create the file path where we will develop our application with the following commands and enter it:
|
1 2 3 |
mkdir exchange-rates-app cd exchange-rates-app |
Now let’s start a project in this folder:
|
1 |
npm init -y |
Then let’s download the ‘axios’ library to our project:
|
1 |
npm install axios |
Code
After making the necessary adjustments and setups, we can now develop our code. To do this, let’s open a file named ‘index.js’ in the application directory and put the following codes in it:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
const axios = require('axios'); // API URL const url = 'https://api.exchangeratesapi.io/v1/latest?access_key=API_KEY&symbols=GBP,JPY,TRY,AUD,AED,QAR'; // Make an API request and handle response axios.get(url) .then(response => { const data = response.data; if (data.success) { const rates = data.rates; console.log("Exchange Rates (Base EUR):"); console.log(`GBP: ${rates.GBP}`); // GBP rate console.log(`JPY: ${rates.JPY}`); // JPY rate console.log(`TRY: ${rates.TRY}`); // TRY rate console.log(`AUD: ${rates.AUD}`); // AUD rate console.log(`AED: ${rates.AED}`); // AED rate console.log(`QAR: ${rates.QAR}`); // QAR rate } else { console.error("API request failed."); // Failure message } }) .catch(error => { console.error("An error occurred during the API request:", error); // Error during request }); |
With this code, we use the latest rates endpoint of exchangeratesapi.io to instantly obtain the values of the selected currencies corresponding to the ‘EUR’ currency.
Test
Before testing the application, let’s put our API key in the ‘API_KEY’ field. Then, let’s start the application by running the following command in a terminal in the application directory:
|
1 |
node index.js |
The response we get after running the application is as follows:
|
1 2 3 4 5 6 7 |
Exchange Rates (Base EUR): GBP: 0.842763 JPY: 167.597108 TRY: 35.826571 AUD: 1.656336 AED: 3.976965 QAR: 3.952885 |
We can obtain the results automatically by running this application at certain intervals with the above command. In addition, saving the results we obtain to a database instead of logging them will make the operational process easier.

Security and compliance are other important issue to consider in currency API integration. Secure transmission and processing of data both protect user information and prevent data leaks. Using secure protocols such as HTTPS provides encryption during data transmission and protects against potential cyberattacks. Moreover, considering compliance requirements in API integration ensures compliance with legal and regulatory standards. Applications such as firewalls, data encryption methods, and regular security scans are important strategies that increase data security.
Scalability and performance are critical to managing high volumes of data requests. Large-scale businesses in particular require that currency APIs be optimized for performance in order to seamlessly process high data volumes. In API integration, implementing efficient data retrieval strategies, even during periods of high demand, minimizes performance issues. Technical solutions such as load balancing, caching, and setting appropriate API call limits regulate data flow and ensure high system performance.
