How have you integrated with external APIs or services in your projects?

To integrate with external APIs in Python, I usually use the requests library, which allows sending HTTP requests (GET, POST, etc.) and receiving responses in a convenient format.

Main steps:

1. Study the API documentation to understand which endpoints are available, what parameters and headers are needed.
2. Formulate the request with the required parameters and headers.
3. Send the request and process the response (usually JSON).
4. Handle errors and exceptions (e.g., timeouts, error codes).

Example of a simple API request:

import requests

url = 'https://api.example.com/data'
params = {'key': 'value'}
headers = {'Authorization': 'Bearer YOUR_TOKEN'}

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

if response.status_code == 200:
    data = response.json()
    print(data)
else:
    print(f'Error: {response.status_code}')

For more complex integrations, I can use libraries for asynchronous requests (aiohttp), handle pagination, cache responses, or use SDKs if provided by the service.
