const amadeus = new Amadeus({
  clientId: 'YOUR_API_KEY',
  clientSecret: 'YOUR_API_SECRET'
});

// Search flights
const flights = await amadeus.shopping.flightOffersSearch.get({

  destinationLocationCode: 'LAX',
  departureDate: '2025-06-15',
  adults: '2',
  currencyCode: 'USD'
});

// Search hotels
const hotels = await amadeus.shopping.hotelOffers.get({
  cityCode: 'PAR',
  checkInDate: '2025-06-15',
  checkOutDate: '2025-06-20',
  adults: 2
});

2. Google Maps Integration

// Places Autocomplete
const searchPlaces = async (query) => {
  const response = await fetch(
    `https://maps.googleapis.com/maps/api/place/autocomplete/json?` +
    `input=${query}&types=(cities)&key=${GOOGLE_API_KEY}`
  );
  return response.json();
};

// Distance Matrix
const getDistance = async (origins, destinations) => {
  const response = await fetch(
    `https://maps.googleapis.com/maps/api/distancematrix/json?` +
    `origins=${origins}&destinations=${destinations}&key=${GOOGLE_API_KEY}`
  );
  return response.json();
};

3. Payment Processing

// Stripe Payment Intent
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);

const createBookingPayment = async (amount, currency, bookingId) => {
  const paymentIntent = await stripe.paymentIntents.create({
    amount: amount * 100, // cents
    currency: currency,
    metadata: {
      bookingId: bookingId
    },
    payment_method_types: ['card'],
  });

  return paymentIntent.client_secret;
};

    description: { type: 'text' },
    city: { type: 'keyword' },
    country: { type: 'keyword' },

  }
};

// Search query
const searchListings = async (params) => {
  const { city, checkIn, checkOut, guests, minPrice, maxPrice, amenities } = params;

  const query = {
    bool: {
      must: [
        { match: { city } },
        { range: { max_guests: { gte: guests } } },
        { range: { base_price: { gte: minPrice, lte: maxPrice } } }
      ],
      filter: [
        {
          geo_distance: {
            distance: '50km',
            location: { lat: params.lat, lon: params.lon }
          }
        }
      ]
    }
  };

  if (amenities?.length) {
    query.bool.must.push({
      terms: { amenities }
    });
  }

  return elasticsearch.search({
    index: 'listings',
    body: { query, sort: [{ average_rating: 'desc' }] }
  });
};
