Sample Python script using Requests for connecting to the new RESTful SugarCRM REST API in 6.7 and later.

gistfile1.py

import json
import requests

url = "<<instanceurl>>/rest/v10/oauth2/token"
payload = {"grant_type":"password","username":"<<username>>","password":"<<password>>","client_id":"sugar"}

r = requests.post(url, data=json.dumps(payload))

response = json.loads(r.text)

if response[u'error']:
    print response[u'error_message']
    
token = response[u'access_token']    
print 'Success! OAuth token is ' + token

url = "<<instanceurl>>/rest/v10/me"
headers = { "Content-Type" : "application/json", "OAuth-Token": token }

r = requests.get(url, headers=headers);

response = json.loads(r.text)

if response[u'error']:
    print response[u'error_message']

print r.json()

    

This will throw exceptions any time the API doesn't return an error (since 'error' won't exist).

Using r.json() seems a bit cleaner than json.loads().
