In what cases is it recommended to use the POST method when sending HTTP requests?

The POST method is recommended to be used in HTTP requests when:

• You need to send data to the server for creating or modifying a resource (e.g., submitting a form, uploading a file).
• The volume or structure of data is too large or complex to be transmitted via URL (as in GET).
• You need to hide data from being visible in the URL (e.g., passwords).
• The operation changes the state of the server or database (creation, update).

Unlike GET, POST is not cached by the browser and does not save data in the URL history, which enhances security and operation correctness.

Example of sending a POST request using Python and the requests library:

import requests

url = 'https://example.com/api/create'
data = {'username': 'user1', 'password': 'secret'}
response = requests.post(url, json=data)
print(response.status_code)
