How To Use ChatGPT API In JavaScript

Do you want to learn how to programmatically use ChatGPT AP in Javascript? Search no further, we will reveal to you the best tips on how to use OpenAI API in Javascript. One of the most amazing things about ChatGPT is the room for implementation, developers can implement ChatGPT in Node.js, JavaScript, and many other programming languages of their choice to spice up their project.

The OpenAI API makes it possible for people to use ChatGPT without login, hence developers can decide whether or not should a user log in to access their ChatGPT-powered apps. So, if you’re new to developing a ChatGPT app and want to know how best you can implement your API key with JavaScript, you will find the following guide helpful.

How to use ChatGPT API with JavaScript – Examples included

Here’s a sure step to creating your own Chatbot using ChatGPT OpenAI key in JS.

Step 1: Sign up for OpenAI API

  • Go to the OpenAI website ( and sign up for an account if you haven’t already.
  • Follow the instructions to create an API key. Make sure you have the necessary permissions to access the ChatGPT API.

Step 2: Set up your JavaScript environment

  • Create a new directory for your project and navigate to it using the terminal.
  • Initialize a new npm project by running the following command: npm init -y.
  • Install the Axios library for making HTTP requests: npm install axios.

Step 3: Set up your API key

  • Create a new file called .env in the root of your project directory.
  • Inside the .env file, add your API key using the following format: API_KEY=your_api_key_here

Step 4: Create a JavaScript file

  • Create a new JavaScript file in your project directory. You can name it whatever you like, for example, chatbot.js.

Step 5: Set up the API request

  • In your chatbot.js file, import the necessary libraries, and retrieve your API key from the .env file. Add the following code at the top of the file:
require('dotenv').config(); // Load environment variables
const axios = require('axios');
const apiKey = process.env.API_KEY;

Step 6: Make a chat API call

  • Below the code from the previous step, add the following code to make a chat API call:
async function generateChatMessage(message) {
  const apiUrl = '';
  const headers = {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${apiKey}`
  const data = {
    'messages': [{'role': 'system', 'content': 'You are a helpful assistant.'}, {'role': 'user', 'content': message}]

  try {
    const response = await, data, { headers });
  } catch (error) {
    console.error('API request error:', error);
    return null;

// Usage example
async function main() {
  const userInput = 'Hello, how can I help you?';
  const response = await generateChatMessage(userInput);
  console.log('ChatGPT response:', response);


Step 7: Run your code

  • Save the chatbot.js file and run it using Node.js by executing the following command in your terminal: node chatbot.js
  • You should see the response from the ChatGPT API logged in the console.

That’s it! You’ve successfully set up the ChatGPT API in JavaScript using the OpenAI API. As a developer, you can modify the code to suit your specific use case and integrate it into your own applications.
