Example client:

import requests

response = requests.post(
    'http://localhost:9999/login',
    json={
        'client_id': 'user',
        'client_secret': 'password'
    }
).json()

token = f"{response['type']} {response['access_token']}"

# option 1 - Headers
requests.get(

Create Token:

from bottlejwt import JwtPlugin

# is a singleton, you only need to initialize once.
# * If you did install () also work
JwtPlugin(validation, 'secret', algorithm='HS256')

print(JwtPlugin.encode({'name': 'pepito'}))
