How to Get Hotel Data with Booking.com API in Python

Understanding Booking.com's Data Structure

• Before accessing Booking.com data, familiarize yourself with its data structure. Booking.com generally provides properties like hotel details, room availability, pricing, reviews, etc.

 

• Read the latest Booking.com API documentation to understand endpoints, request methods, and data returned.

Install Required Libraries

• To interact with the Booking.com API using Python, install libraries such as `requests` for handling HTTP requests and `json` for working with JSON data. You can install these using pip:

pip install requests

Authenticate and Set Up Your First API Call

• Once you have the required credentials (API key, username, etc.), you can set up a basic `GET` request to an endpoint. Ensure to add your API key in the headers for authentication.

 

• Here's a basic example to fetch hotels data:

import requests

# Define endpoint and headers
url = 'https://api.booking.com/hotels'
headers = {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
}

# Send GET request and parse response
response = requests.get(url, headers=headers)
data = response.json()

# Display part of the data
print(data)

Handle API Rate Limits and Errors

• When integrating with the Booking.com API, watch out for API rate limits that could restrict the number of requests. The API documentation usually outlines these limits.

 

• Implement error handling to manage situations like invalid requests or exceeding rate limits. A simple try-except block could be employed:

try:
    response = requests.get(url, headers=headers)
    response.raise_for_status() # Raises an HTTPError for bad responses
    data = response.json()
except requests.exceptions.HTTPError as err:
    print(f"HTTP error occurred: {err}")
except Exception as err:
    print(f"Other error occurred: {err}")

Parse and Use the Data

• Once you have the data, extract the information relevant to your needs. This might include hotel name, address, price, or availability.

 

• You can filter, sort, and save the data locally or feed it into a data processing pipeline for further analysis. Here’s how to parse out hotel names:

# Assuming 'data' contains a list of hotels
hotels = data.get('hotels', [])

# Iterate through hotels and print names
for hotel in hotels:
    print(hotel.get('name'))

Maintain API Security and Efficiency

• Keep your API keys secure. Do not hard-code them in your scripts. Use environment variables or secure configuration files.

 

• Aim for efficient data retrieval. Use parameters to limit the data returned by the API, and request only the fields you need. Here’s an example using query parameters:

params = {
    'location': 'New York',
    'check_in': '2024-01-01',
    'check_out': '2024-01-05',
    'limit': 10
}

response = requests.get(url, headers=headers, params=params)
data = response.json()
