I want to edit signatures of users in a google apps domain.
I plan to use a service account. The service account is delegated to the entire domain.
I have this working with the gmail API to send and retrieve email, but signatures are modified using a different api.
According to https://developers.google.com/admin-sdk/email-settings/ this api is the Admin SDK which I have enabled via Google Developer Console.
I am trying to use the library
gdata.apps.emailsettings.client (which doesn't have Python 3.x support)
Building the credentials works, but when I try to do
# python 2.7 from macports
client_email = '...email@example.com'
key_path = 'VCI-EMAIL-INTEGRATION-f493528321ba.json'
sender = 'firstname.lastname@example.org'
API_scope = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/'
credentials = ServiceAccountCredentials.from_json_keyfile_name(key_path, scopes=API_scope)
if __name__ == "__main__":
credentials = setup_gmail_client_new_api()
client = gdata.apps.emailsettings.client.EmailSettingsClient(domain='vci.com.au')
auth = gdata.gauth.OAuth2Token(
result = retrieve_sig(client,"tim")
gdata.client.Unauthorized: Unauthorized - Server responded with: 401,
Right. I hope this post saves hours of work.
Key missing point which was not documented very well (ok, not at all, but perhaps I missed it). You need to use delegated_credentials and authorise the email_settings_client with that object.
Now, the python code. I used 2.7 because I think gdata is not v3 compatible.
This is a minimal example.
from __future__ import print_function import httplib2 from oauth2client.service_account import ServiceAccountCredentials import gdata.apps.emailsettings.client import gdata.gauth def setup_credentials(): key_path = '/Users/tim/Dropbox/pycharm_projects_27/gmail_admin/<blabla>.json' API_scopes =['https://apps-apis.google.com/a/feeds/emailsettings/2.0/'] credentials = ServiceAccountCredentials.from_json_keyfile_name(key_path, scopes=API_scopes) return credentials if __name__ == "__main__": credentials = setup_credentials() # pass the email address of a domain super-administrator delegated_credentials = credentials.create_delegated('email@example.com') http = httplib2.Http() #http = credentials.authorize(http) http = delegated_credentials.authorize(http) #this is necessary url_get_sig = 'https://apps-apis.google.com/a/feeds/emailsettings/2.0/vci.com.au/tim/signature' r = http.request(url_get_sig,"GET") print (r) # now use the library client = gdata.apps.emailsettings.client.EmailSettingsClient(domain='vci.com.au') auth2token = gdata.gauth.OAuth2TokenFromCredentials(delegated_credentials) auth2token.authorize(client) r = client.retrieve_signature('tim') print (client)
