Using the Gmail API with Python

The Gmail API allows developers to read, send, and manage emails programmatically. Here's a basic example of how to use the Gmail API with Python to list the user's emails.

   from googleapiclient.discovery import build   from google.oauth2 import credentials    # Authenticate with the Gmail API (requires setting up credentials)   creds = credentials.Credentials.from_authorized_user_file('token.json', ['https://www.googleapis.com/auth/gmail.readonly'])    service = build('gmail', 'v1', credentials=creds)    # Call the Gmail API to list emails   results = service.users().messages().list(userId='me', maxResults=10).execute()   messages = results.get('messages', [])    if not messages:   print('No messages found.')   else:   print('Messages:')   for message in messages:   print(message['id'])   

This code snippet demonstrates how to authenticate with the Gmail API and retrieve a list of message IDs. Remember to install the necessary libraries (google-api-python-client, google-auth-httplib2, google-auth-oauthlib) and set up your API credentials correctly before running this code.

Creating Gmail Add-ons with Google Apps Script

Google Apps Script allows you to create custom add-ons that integrate directly into Gmail. Here's an example of a simple add-on that adds a custom button to the Gmail interface.

   /**   * Creates a menu entry in the Gmail UI when the add-on is installed.   *   * @param {object} e The event parameter for the onOpen event.   */   function onOpen(e) {   GmailApp.createAddOnMenu()   .addItem('Custom Action', 'showSidebar')   .addToUi();   }    /**   * Shows add-on sidebar.   */   function showSidebar() {   var ui = HtmlService.createHtmlOutputFromFile('Sidebar')   .setTitle('My Custom Add-on');   GmailApp.getUi().showSidebar(ui);   }   

This script defines two functions: `onOpen`, which creates a custom menu item when the add-on is installed, and `showSidebar`, which displays a sidebar with custom HTML content. This example provides a foundation for building more complex Gmail add-ons with custom functionality.

Node.js Example: Sending Emails with Nodemailer

For server-side email sending, Node.js and the Nodemailer library provide a robust solution. Here's a simple example of sending an email using Nodemailer.

   const nodemailer = require('nodemailer');    // Create a transporter object using the default SMTP transport   let transporter = nodemailer.createTransport({   host: 'smtp.example.com',   port: 587,   secure: false, // true for 465, false for other ports   auth: {   user: 'your_email@example.com', // your email address   pass: 'your_password' // your email password   },   });    // setup email data with unicode symbols   let mailOptions = {   from: 'your_email@example.com', // sender address   to: 'recipient@example.com', // list of receivers   subject: 'Hello from Nodemailer', // Subject line   text: 'Hello world?', // plain text body   html: '<p>Hello world?</p>' // html body   };    // send mail with defined transport object   transporter.sendMail(mailOptions, (error, info) => {   if (error) {   return console.log(error);   }   console.log('Message sent: %s', info.messageId);   });   

This code snippet demonstrates how to send emails using Node.js and Nodemailer. Remember to replace the placeholder values with your actual email address, password, and SMTP server details. Nodemailer supports various transport methods, including SMTP, Sendmail, and more.
