HTTP Request Message

import requests


api_url = "https://example.com/api"
params = {'key_1': 'value_1', 'key_2': 'value_2'}
header = {'User-Agent': 'MyApp/1.0', 'Authorization': 'Bearer SomeToken'}
data = {'usr_name': 'JohnDoe', 'usr_pwd': 'SomePassword'}

response = requests.post(
    url,
    params=params,
    headers=headers,
    data=data, # or json=data
)

This will generate the following HTTP request message
