What the Google Tasks API Provides

REST API for task lists and items

Create, read, update, and delete task lists and tasks via standard HTTP requests. The API mirrors what you can do in the Google Tasks app.

OAuth 2.0 authentication

Apps request scoped access through Google's OAuth consent screen. Users grant permission per account, no passwords are shared with third parties.

Real-time two-way sync

Changes made through the API appear in Gmail, Calendar, and mobile instantly. TasksBoard uses the API to keep boards in sync with Google Tasks.

Zapier and automation support

Connect Google Tasks to thousands of apps via Zapier, Make, or custom scripts using the same API endpoints and OAuth flow.

Authentication

Authentication

OAuth 2.0: how apps connect to Google Tasks

Third-party apps like TasksBoard use OAuth 2.0 to request access to your Google Tasks data. You sign in with Google, review the requested scopes, and grant permission. TasksBoard requests only the Google Tasks API scope, it does not access Gmail, Drive, or other Google services unless you explicitly enable those features.

Standard Google OAuth consent screen
Scoped to Google Tasks read/write only
Revoke access anytime from Google Account settings

REST endpoints

Core Google Tasks API resources

REST endpoints

Core Google Tasks API resources

The API exposes two main resources: task lists and tasks. You can list all task lists, create new ones, and manage tasks within each list including title, notes, due date, and completion status. The base URL is https://tasks.googleapis.com/tasks/v1/ with standard REST verbs: GET, POST, PATCH, and DELETE.

tasks.tasklists, manage named lists
tasks.tasks, create, update, complete, and delete tasks
Subtasks supported via parent task relationships

Integrations

Zapier, automation, and TasksBoard security

Use Zapier to trigger Google Tasks from Slack messages, form submissions, or CRM updates. For a visual interface on top of the API, TasksBoard provides Kanban boards and team sharing without writing code. Read the TasksBoard security page for details on data handling, OAuth scopes, and compliance.

How to integrate with the Google Tasks API

Create a Google Cloud project

Enable the Google Tasks API in Google Cloud Console, configure OAuth consent, and create credentials for your app or script.
Authenticate with OAuth 2.0

Request the https://www.googleapis.com/auth/tasks scope. Users authorize your app through Google's consent screen and receive an access token.
Call REST endpoints or use TasksBoard

Use the Tasks API directly for custom integrations, Zapier for no-code automation, or TasksBoard for a ready-made Kanban interface on top of Google Tasks.

"Always have 101 things to do and this helps me organize and prioritize like no other app can. It syncs to my phone and laptop, and when I add dates to tasks, they automatically integrate into my Google Calendar, which is immensely convenient. I can look at my daily, weekly, and monthly overview in Google Calendar and clearly see how much I was able to accomplish! Great tool indeed. Excited to see how it will evolve over time."

Parina Ramjee

"Seriously, makes my tasks easier to share with the team, and the free version is quite nice for our little office. Eventually, we will expand, and this is definitely a great tool to do that! Syncs with my Workspace and Calendar."

Chase Cattrall

"I love the simple, intuitive interface and the Add to Tasks feature, especially as I work through my emails! Sharing my tasks is also easy. Overall, outstanding and simple to use, and that means a lot with too many complex tasks out there!"

Greg Cantori

"Great too for managing daily routine and plan tasks. Would be perfect if it was updated for generating reports for statistics. For google tasks and google calendar"

"This extension makes it so much easier for me to quickly add a task while I'm doing anything on the web. Conveniently pops out of the side of the browser window when I need it, and when I'm done with my task, I can quickly pop it right back out of sight. Love it!"

Joshua Beach (M. Lé)

"I use it in combination with a widget on my phone so I can put things down that enter my mind right away and later organize it in my important/urgent martix. Does the job easily enough. Haven't played around with any advanced features."

Nicholas Austin

"Well, this service is just awesome, I get to access my task list very easily at any time I want when working on my computer. No matter what im working on, atleast one browser tab is open in chrome. You can add it on top there for quick access, its just lovely, I gave 4 stars (you deserve a 5) but perhaps that will be a room for improvement. L'chaim 🥂"

"Very happy with TasksBoard! We use it as a family to manage the chaos. Also, we have found added benefit in the premium version, so we finally took the plunge. No regrets! It has helped us be more intentional in coordinating and communicating all the little things that used to fall through the cracks. We are very grateful for this product!"

Michael Barnett

"Having the ability to share a google tasks list has been priceless and really helped me to streamline the jobs I have coming in. Would highly recommend the app if you are working between two or more google accounts."

Stirling Moss

"Good for getting work done. Turned my written lists into task lists on Tasksboard. Helps me keep track of notes, dates, conversations, links and 'all the things' related to each project."

Tasha Nesbitt

"It doesn't recognize Google's built-in recurrence, and that has proven to be costly to me and the company significantly. The tool functions as promised; it is worth the small fee. But if I find something better, I will switch unless this integration improves."
