ChatGPT Chatbot: Step-by-Step Guide to building your chatbot.

Step 1 - Prepare your HTML Structure.

You will need to set up a plain container containing the chatbot in your site:

<div id="chatbot-container">
  <div id="chat-messages"></div>
  <input type="text" id="user-input" placeholder="Type your message here..." />
  <button id="send-button">Send</button>
</div>

Hint: CSS can be used to make the chatbot container, messages, and input box appear more user-friendly.

Step 2 - Add Basic Styling

<style>
#chatbot-container {
  width: 350px;
  border: 1px solid #ccc;
  border-radius: 8px;
  padding: 10px;
  background: #f9f9f9;
  font-family: Arial, sans-serif;
}
#chat-messages {
  height: 300px;
  overflow-y: auto;
  margin-bottom: 10px;
  padding: 5px;
  border: 1px solid #ddd;
  background: #fff;
}
#user-input {
  width: calc(100% - 80px);
  padding: 8px;
}
#send-button {
  padding: 8px 12px;
  margin-left: 5px;
  cursor: pointer;
}
.user-msg {
  text-align: right;
  color: #0077cc;
  margin: 5px 0;
}
.bot-msg {
  text-align: left;
  color: #333;
  margin: 5px 0;
}
</style>

Step 3 - Interlink with the ChatGPT API.

Send the user input to ChatGPT API with the help of JavaScript and show responses:

<script>
const apiKey = 'YOUROPENAIAPI_KEY'; // enter in your key.
const sendButton = document.getElementById('send-button');
const userInput = document.getElementById('user-input');
const chatMessages = document.getElementById('chat-messages');

sendButton.onclick = async function() {
  const message = userInput.value;
  if (!message) return;

  // Display user message
  const userMsgDiv = document.createElement('div');
  userMsgDiv.className = 'user-msg';
  userMsgDiv.textContent = message;
  chatMessages.appendChild(userMsgDiv);

  userInput.value = '';

  // Call ChatGPT API
  const response = await fetch('https://api.openai.com/v1/chat/completions', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${apiKey}`
    },
    body: JSON.stringify({
      model: "gpt-3.5-turbo",
      messages: [{ role: "user", content: message }]
    })
  });

  const data = await response.json();
  const botMsgDiv = document.createElement('div');
  botMsgDiv.className = 'bot-msg';
  botMsgDiv.textContent = data.choices[0].message.content;
  chatMessages.appendChild(botMsgDiv);

  chatMessages.scrollTop = chatMessages.scrollHeight;
};
</script>

Hint: Do not present your API key in a public environment. Proxying to a server-side for security.

Step 4 - Test Your Chatbot

• Open your website via a browser.
• Enter a type a message in the chatbot input box and press send.
• Test whether ChatGPT can reply correctly.

Step 5 - Advanced Tips
