Understanding the Gmail Add-ons development process

The development of Gmail add-ons is a structured process that integrates coding, system integration, and adherence to Google's guidelines. The following provides a comprehensive overview of the Gmail add-ons development process:

-> Establishing the Development Environment

Before engaging in coding activities, developers must configure their development environment. This includes initiating a project in the Google Cloud Console, enabling the Gmail API, and acquiring essential API credentials. Additionally, developers must choose a programming language for their add-on, with options like Apps Script (JavaScript) or other languages supported by Google APIs.

-> Defining Add-on Functionality

Here is a pivotal stage of the development that involves defining the add-on's functionality clearly. Coders work to identify the specific tasks the add-on will perform within the Gmail interface, ranging from automating actions to incorporating third-party services for enhanced features.

-> Coding and Implementation

Next, it comes to building upon the outlined functionality, so developers will start coding the add-on. When employing Apps Script, programmers craft JavaScript code to create functions that interact with Gmail and external APIs. Moreover, ensuring alignment with Google's security and privacy requirements is also paramount.

-> Comprehensive Add-on Testing

Rigorous testing is imperative to identify and rectify bugs or issues. Developers test the add-on across diverse scenarios to ensure seamless functionality across various email types, devices, and Gmail settings.

-> Submission and Approval for Add-on

Upon successful testing, developers submit the add-on for review through the Google Workspace Marketplace. Google evaluates the add-on to verify compliance with guidelines, encompassing security and usability standards. Following approval, the add-on becomes accessible for users to install

-> Gmail Add-on Deployment and Maintenance

The last stage involves post-approval and the add-on is deployed to the Google Workspace Marketplace. Developers have to remain attentive, constantly monitor user feedback, address reported issues, and potentially update the add-on to introduce new features or enhancements.

What Tools and technologies are used for Gmail Add-on development

Gmail add-on development involves a combination of tools and technologies that enable developers to create seamless integrations with Gmail and enhance its functionalities. Here's a concise overview of the key tools and technologies commonly used in the development process:

Google Apps Script (GAS)

Google Apps Script stands at the core of the Gmail add-on development which is a scripting language based on JavaScript. This server-side scripting language is provided by Google and enables developers to create custom functions, automate tasks, and interact with Google Workspace applications, including Gmail. And guess what? This technology is also used for Google Sheets Add-ons development.

Google Workspace Marketplace SDK

This software development kit allows the publication and allocation of Gmail add-ons. Developers employ the SDK to create, manage, and deploy their add-ins to the Google Workspace Marketplace, making them accessible to a broader audience.


User interface design is a crucial aspect of Gmail add-on development. HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are fundamental web development languages used to structure and style the graphical user interface (GUI) of the add-ons. This ensures a visually appealing and user-friendly experience for the end-users.

Google Cloud Platform (GCP)

Developers leverage the Google Cloud Platform for various cloud services such as storage, authentication, and data analysis. GCP ensures the reliability and scalability of Gmail add-ons, providing a robust infrastructure for storing and processing data securely.

OAuth 2.0

Security is paramount in Gmail add-on development, and OAuth 2.0 is a widely used protocol for secure authorisation. It allows third-party applications, in this case, Gmail add-ons, to access Gmail user data without exposing sensitive credentials. OAuth 2.0 ensures a secure and standardized way of authenticating users.
