ArcGIS REST unable to updateDefinition

Hi, using the REST API, I'm attempting to update multiScaleGeometryInfo for my feature layers, but I'm having trouble getting into the updateDefinition URL. Here's the error I get:

{u'error': {u'message': u'Unable to update feature service layer definition.', u'code': 400, u'details': [u'Value cannot be null. Parameter name: input']}}

Here's my Python script. Thanks for any help!

import sys
import ntpath
import os, sys, json, urllib, urllib2, httplib, urlparse, mimetools, mimetypes
from cStringIO import StringIO

username = "un"
password = "pw"

tokenURL = "https://www.arcgis.com/sharing/generateToken"
params = {'f': 'pjson', 'username': username, 'password': password, 'referer': 'https://services7.arcgis.com'}
req = urllib2.Request(tokenURL, urllib.urlencode(params))
try:
   response = urllib2.urlopen(req)
except:
   gcontext = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
   response = urllib2.urlopen(req, context=gcontext)
data = json.load(response)
token = data['token']
print(token)
requesturl = "https://services7.arcgis.com/[ID]/ArcGIS/rest/admin/services/example/FeatureServer/0/updateDefinition"
#data = {'f': 'json', 'token': sh.token, "multiScaleGeometryInfo" : {"levels" : [7,9,11,13,15]}} #this is what I'll eventually do
data = { "f": "json", "token": token}
query_string = urllib.urlencode(data)
print query_string

response = urllib.urlopen(requesturl, query_string)
resp_json = json.loads(response.read())
print resp_json

I figured it out. Need to have async=true, and add the updateDefinition parameter.

This is the corrected line:

data = { "f": "json", "token": token, "async": "true", "updateDefinition": {"multiScaleGeometryInfo": {"levels" : [7,9,11,13,15]}}}
