Main_type, sub_type = content_type.split('/', 1) If content_type is None or encoding is not None:Ĭontent_type = 'application/octet-stream' This will prompt you in your default browser to accept the permissions required for this app, if you see a window that indicates the app isn't verified, you may just want to head to Advanced and click on go to Gmail API Python (unsafe):įirst, let's start with the function that sends emails, we know that emails can contain attachments, so we will define a function that adds an attachment to a message, a message is an instance of MIMEMultipart (or MIMEText, if it doesn't contain attachments): # Adds the attachment with the given filename to the given messageĬontent_type, encoding = guess_mime_type(filename)

You should see this familiar if you already used a Google API before, such as Google drive API, it is basically reading the credentials.json and saving it to token.pickle file after authenticating with Google in your browser, we save the token so the second time we run the code we shouldn't authenticate again. Return build('gmail', 'v1', credentials=creds) With open("token.pickle", "wb") as token: If creds and creds.expired and creds.refresh_token:įlow = om_client_secrets_file('credentials.json', SCOPES) # if there are no (valid) credentials availablle, let the user log in. With open("token.pickle", "rb") as token: # created automatically when the authorization flow completes for the first time # the file token.pickle stores the user's access and refresh tokens, and is Obviously, you need to change our_email to your address, make sure you use the email you created the API auth with.įirst of all, let's make a function that loads the credentials.json, does the authentication with Gmail API and returns a service object that can be used later in all in our upcoming functions: def gmail_authenticate(): # Request all access (permission to read/send/receive emails, manage the inbox, and more) # for dealing with attachement MIME typesįrom import MIMEMultipartįrom mimetypes import guess_type as guess_mime_type # for encoding/decoding messages in base64įrom base64 import urlsafe_b64decode, urlsafe_b64encode Now we're done with setting up the API, let's start by importing the necessary modules: import osįrom googleapiclient.discovery import buildįrom google_auth_oauthlib.flow import InstalledAppFlowįrom import Request Note: If this is the first time you use Google APIs, you may need to simply create an OAuth Consent screen and add your email as a testing user.

We download our credentials file and save it as credentials.json in the current directory: Select Desktop App as the Application type and proceed, you'll see a window like this: We then create an OAuth 2.0 client ID by creating credentials (by heading to the Create Credentials button): We first enable the Google mail API, head to the dashboard, and use the search bar to search for Gmail API, click on it, and then enable: To use the Gmail API, we need a token to connect to Gmail's API, we can get one from the Google APIs' dashboard.

To get started, let's install the necessary dependencies: $ pip3 install -upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib Enabling Gmail API $ python mark_emails.py -unread "search query" $ python mark_emails.py -read "search query" While the previous tutorials were on using the IMAP/SMTP protocols directly, in this one, we will be using Google's API to send and read emails, by doing so, we can use features that are specific to Google Mail, for example add labels to some emails, mark emails as unread/read and so on.įor this guide, we will explore some of the main features of the Gmail API, we will write several Python scripts that have the ability to send emails, search for emails, deletes, and mark as read or unread, they'll be used as follows: $ python send_emails.py "Subject" "Message body" -files file1.txt file2.pdf file3.png In the previous tutorials, we explained how you can send emails as well as reading emails with Python, if you didn't read them yet, I highly recommend you check them out. Many of its features are enhanced with AI, including its security (and detection of fraudulent emails) and its suggestions when writing emails. Gmail is by far the most popular mail service nowadays, it's used by individuals and organizations.
