Build on G Suite.

Supercharge your team.

G Suite is a set of applications, including Gmail, Docs, Sheets, Slides, Sites and more, as well as a set of messaging, collaboration, security, and compliance tools for organizations to use. The G Suite Developer Platform is a collection of tools and resources that let you integrate your software with G Suite and its users, or create new apps that run entirely within G Suite.

APIs & libraries

  • REST APIs for Sheets, Slides, Gmail, Calendar, People, Drive, Directory, Reports, Vault, Hangouts Chat, Sites, and many more app and admin APIs.
  • Client libraries for using these APIs natively in Java, .NET, PHP, Python, JavaScript, and other popular languages.

Development tools

  • Apps Script: Essentially JavaScript that's G Suite aware, with powerful built-in modules for manipulating G Suite apps and data.
  • App Maker: A low-code/no-code way to quickly build custom apps for your G Suite domain.

Marketing tools

  • G Suite Marketplace: an ecosystem for distributing and monetizing your custom G Suite apps and add-ons.
  • Analytics: to help you track customer adoption of your app.

Build on top of G Suite with Apps Script

Google Apps Script is a customized JavaScript serverless runtime featuring tight integration with G Suite & other Google services. It's a great way to automate common tasks, extend the functionality of the editors (Docs, Sheets, Slides, Forms), and create other integrations with Google and external services. Apps Script is also the technology that powers G Suite Add-ons and App Maker.

Create data-driven solutions with Sheets

Not only can you get your data flowing in or out of Sheets, but you can also tap into features such as formatting data, pivot tables, data validation, filter views, embedded charts, and conditional formatting. Leverage Sheets from its REST API or from Google Apps Script which is also the technology that powers Sheets Add-ons.

Build a variety of integrations with Gmail

Integrate Gmail into your application using its flexible REST API. Or, integrate your app into Gmail by creating a Gmail Add-on where users can access your app's functionality from right within Gmail. Email markup turns ordinary messages into structured action items when rendered in Gmail.

Integrate your services with Hangouts Chat

Build on the Chat platform to streamline interactions and automate workflows across teams. Create chatbots (think microservice utility apps) to query for information or integrate services using a conversational interface.

Backup your app data with Drive

The Drive API lets you sync data from your app with your user's Google Drive account, so it's available everywhere. The Drive API is also the right tool for creating, copying, and importing/exporting files, as well as changing file permissions in Drive.

APIs for interacting with G Suite

Our REST APIs let your app integrate with users' mail, calendars, contacts, and other data.

Google Drive Activity API

Track changes to a user's Google Drive files, including new comments and other activity.

Calendar API

Create new events in a user's Google Calendar, edit or delete existing events, and search for events.

Contacts API

Drive API

Interact with nearly any aspect of a user's Google Drive, including permissions, file revisions, and connected apps.

Gmail API

Picker API

Sheets API

Create and manage nearly every aspect of Google Sheets data, including the content, arrangement and appearance.

Docs API

Read and modify the content of Google Docs: implement use cases like bulk document generation, content management, and workflow management.
