ConcurOAuthPython.py

import requests
import json
import base64

baseUrl = 'https://www.concursolutions.com'
oauthUrl = baseUrl+'/net2/oauth2/accesstoken.ashx'
reportDigestUrl = ''


def getbasic(user, password):
    # basic authentication (according to HTTP)
    return base64.encodestring(user + ":" + password)    

 
def getTokenGivenUsernamePasswordAndConsumerKey(username, password, consumerKey):
	"""
	Given: 
		String username (Concur username)
		String password (Concur password)
		String ConsumerKey (Registered partner applciation consumerKey)

	Example: 
		Python dictionary of the Oauth Response:
		getTokenGivenUsernamePasswordAndConsumerKey('example@concur.com', '12345', 'ConsumerKey')
		{u'Access_Token': {u'Expiration_date': u'5/7/2015 10:17:14 PM', u'Token': u'NhYhZsP1zK1sARLHkWqSJpwfBIw=', 
		u'Instance_Url': u'https://www.concursolutions.com/', u'Refresh_Token': u's9Scoa2GdFkjQYFRgsXKrdcwJBrgIan'}}

		You can then save this token and use it in the headers of your HTTP calls with the parameter: 
		Authorization: OAuth {Token}

	""" 
	basic = 'Basic ' + getbasic(username, password)
	headers1 = {'Authorization': basic.rstrip(), 'X-ConsumerKey': consumerKey, 'Accept':'application/json'}
	r = requests.get(oauthUrl, headers=headers1)
	return json.loads(r.content)
