Where Do I Get The Authorized Gmail Api Service Instance? (python, Gmail Api)

I'm trying to call from my gmail api code so I can create a draft, but I can't figure out where to get the 'Authorized Gmail API service instance.' Here's my code: def CreateDraft

Solution 1:

So I figured it out. I did the following:

1) Change SCOPES to:

SCOPES = 'https://mail.google.com/'

2) On your computer (Windows 7) go to "C:\Users\YOURUSERNAME\.credentials

3) Delete the file "gmail-quickstart"

4) Run the code again (quickstart.py)

5) When the message pops up in your browser, click accept.

6) Check mail, you should have your message in there if you're looking to send email through the api.

The credentials file seems to hold the permissions. Changing your permissions and then deleting that file seems to make it all work perfectly. So overall your code should look something like this if you were looking to send mail through the api:

from oauth2client import client
from oauth2client import tools

try:
    import argparse
    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None

SCOPES = 'https://mail.google.com/'
CLIENT_SECRET_FILE = 'client_secret.json'
APPLICATION_NAME = 'Gmail API Quickstart'defget_credentials():
    """Gets valid user credentials from storage.

    If nothing has been stored, or if the stored credentials are invalid,
    the OAuth2 flow is completed to obtain the new credentials.

    credential_path = os.path.join(credential_dir,
                                   'gmail-quickstart.json')

    store = oauth2client.file.Storage(credential_path)
    credentials = store.get()
    ifnot credentials or credentials.invalid:
        flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent = APPLICATION_NAME
        if flags:
            credentials = tools.run_flow(flow, store, flags)
        else: # Needed only for compatability with Python 2.6
            credentials = tools.run(flow, store)
        print'Storing credentials to ' + credential_path
