Hi am trying to connect odoo via Rest API all the credentials was correct still am getting this error. Xmlrpc is working fine. 

import requests

url = 'http://x.x.x.x:8069'

headers = {
'content-type': 'application/json',
'charset':'utf-8'
}

username = 'admin'

data = {
'params':{
'fields': ['id','password'],
'domain': [('login','=', username)],
}

session = requests.Session()

​try:
    session.get('%s/api/res.users'%url, data=data, headers=headers)
except ConnectionError as ce:
    print(ce)
