Getting eBay Access Token (Exchanging auth token) with python requests

Question

I'm trying to use this guide to get access token.

Here is my main file:

import requests
from utils import make_basic_auth_header, conf
code = '<Auth code here>'
url = "%s/identity/v1/oauth2/token" % conf('EBAY_API_PREFIX')
headers = {
 'Content-Type': 'application/x-www-form-urlencoded',
 'Authorization': make_basic_auth_header()
 }
data = {
 'grant_type': 'authorization_code',
 # 'grant_type': 'refresh_token',
 'state': None,
 'code': code,
 'redirect_uri': conf('EBAY_RUNAME')
}
r = requests.post(
 url,
 data=data,
 headers=headers,
)

Here's the make_basic_auth_header() function:

def make_basic_auth_header():
 auth_header_payload = '%s:%s' % (conf('EBAY_APP_ID'), conf('EBAY_CERT_ID'))
 auth_header_base64 = base64.b64encode(auth_header_payload)
 auth_header = 'Basic %s' % auth_header_base64
 return auth_header

But all I get in r.json() is:

{u'error_description': u'request is missing a required parameter or malformed.', u'error': u'invalid_request'}

I'm frustrated - what am I doing wrong?

• Dmitry Arkhipenko: Addition: my files has python2 strings - not unicode. I've also tried switching to unicode - it didn't help
• etemple1: Have you tried passing the data dict as a json formatted str? E.g. after import json data=json.dumps(data)
• user1991179: It looks like the ebay link is a dead link now and I'm having trouble getting the oauth process to work. What is the "auth code" above meant to be?
