// Create a PaymentIntent
app.post('/create-payment-intent', async (req, res) => {
  try {
    const paymentIntent = await stripe.paymentIntents.create({
      amount: 1000, // Amount in cents
      currency: 'usd',
      payment_method_types: ['card'],
    });
    
    res.send({
      clientSecret: paymentIntent.client_secret,
    });
  } catch (error) {
    res.status(500).send({ error: error.message });
  }
});

How it helps: AI generates a clear and functional API request, complete with error handling, making it easy to implement a secure payment flow with Stripe.

3. Integrating Map Services (Google Maps API)

Incorporating maps into applications is essential for services like location-based apps, travel, and logistics. Google Maps API allows developers to integrate location data, geocoding, and even route mapping. AI can help generate code to integrate Google Maps into your web or mobile app.

How AI Assists:

• Requesting API Setup: AI can generate JavaScript code to embed interactive maps, place markers, and display data like weather or location-specific information.
• Real-Time Data: It can also integrate features like real-time traffic or distance calculations using the API.

Example Prompt:

“Generate JavaScript code to integrate Google Maps API and show a map with markers for several locations.”

Generated Code:

function initMap() {
    const map = new google.maps.Map(document.getElementById("map"), {
        zoom: 10,
        center: { lat: 37.7749, lng: -122.4194 }, // San Francisco
    });

    const locations = [
        { lat: 37.7749, lng: -122.4194, title: 'San Francisco' },
        { lat: 34.0522, lng: -118.2437, title: 'Los Angeles' }
    ];

    locations.forEach(location => {
        new google.maps.Marker({
            position: { lat: location.lat, lng: location.lng },
            map,
            title: location.title
        });
    });
}

// Load Google Maps API dynamically
let script = document.createElement('script');
script.src = `https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap`;
document.head.appendChild(script);

How it helps: AI automates the integration of Google Maps, saving you from having to manually write out the logic for map rendering, marker placement, and interaction.

4. Integrating Social Media Feeds (Twitter API)

Social media feeds, such as displaying tweets or posts, can enhance the user experience. Integrating Twitter’s API into your app is a great way to show real-time posts or handle interactions programmatically.

How AI Assists:

• Requesting API Code: AI can generate code to interact with Twitter’s API, retrieve tweets, and display them in a customized format on your website or app.
• Authentication: It can also help with authentication, including handling OAuth tokens to securely access user accounts or public Twitter feeds.

Example Prompt:

“Generate Python code to integrate Twitter API and retrieve the latest tweets from a specific hashtag.”

Generated Code:

import tweepy

# Set up OAuth authentication
auth = tweepy.OAuth1UserHandler(
    consumer_key='YOUR_CONSUMER_KEY',
    consumer_secret='YOUR_CONSUMER_SECRET',
    access_token='YOUR_ACCESS_TOKEN',
    access_token_secret='YOUR_ACCESS_TOKEN_SECRET'
)

api = tweepy.API(auth)

# Retrieve tweets with a specific hashtag
tweets = api.search_tweets(q='#AI', count=10)

for tweet in tweets:
    print(f'{tweet.user.name}: {tweet.text}')

How it helps: AI assists in handling the complexities of OAuth authentication and simplifies fetching and displaying real-time social media data with minimal effort.

5. Handling Authentication and Security

One of the critical aspects of integrating APIs is ensuring secure authentication. Many APIs require API keys, OAuth tokens, or other methods to verify the user’s identity.

How AI Assists:

• API Key Generation and Management: AI tools can guide developers on securely managing API keys, making recommendations on how to store them (e.g., using environment variables).
• OAuth Flow: If the API requires OAuth authentication, AI can generate the necessary code to handle the flow, including obtaining tokens and using them to make authenticated API requests.

Example Prompt:

“Generate code to implement OAuth 2.0 authentication for Google APIs in a Node.js app.”

  'YOUR_CLIENT_ID',
  'YOUR_CLIENT_SECRET',
  'YOUR_REDIRECT_URL'
);

// Get the auth URL
const authUrl = oauth2Client.generateAuthUrl({
  access_type: 'offline',
  scope: ['https://www.googleapis.com/auth/drive.readonly'],
});

console.log('Authorize this app by visiting this url:', authUrl);

How it helps: AI provides you with the boilerplate code for handling OAuth authentication securely, ensuring that your app can access APIs like Google Drive or other services with proper authorization.

6. Real-Time Data Integration

AI can also assist in real-time data integration when dealing with APIs that require constant updates. This could involve APIs like weather services, stock market feeds, or sensor data.
