Google Tasks
Add Google Tasks to your product for your customers, and give your AI agents governed access to it.
Google Tasks is the smallest useful task API Google publishes, and its shape is worth knowing before you build on it. There are task lists, and tasks inside them, and a task carries a title, notes, a due date, a status and a parent, which is how a subtask is expressed. Position is a sort key rather than an index, so moving a task is its own call and not a field write. Two limits catch people out: due is a date rather than a moment, so the time component is ignored no matter what you send, and there are no webhooks at all, so keeping in step means asking for what changed since a timestamp instead of being told. Tasks assigned from Chat or Docs arrive with their assignment information attached but are edited where they originated. Authorisation is per person, so the only lists in scope are the ones that individual keeps.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Have each person authorise their own account, so a task your product files turns up in the list they genuinely check.
Create subtasks by setting a parent, and reorder with an explicit move rather than by writing a position value.
Set a due date knowing Tasks treats it as a date, so your product does not promise a reminder at a time it will ignore.
Ask for tasks changed since a timestamp instead of re-reading every list, since Google Tasks has no webhooks to subscribe to.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent lists what is overdue across a customer's task lists and proposes an order to work them in.
An agent creates a task with notes and a due date within scoped permissions, and the list it wrote to is recorded.
An agent marks a task complete once the work it tracked has been confirmed done.
Example prompt
What is overdue across my task lists, and are any of them subtasks of something already finished?
Set up Google Tasks in 4 steps
- 01Enable the Google Tasks connector in your fastn dashboard.
- 02Have each customer authorise their own Google account, so your product only sees the task lists that person owns.
- 03Decide which lists your product writes to, how subtasks map to parents, and how often you ask for changes since your last read.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Google Tasks integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Google Tasks integration without building it. Your customers connect their own Google Tasks account inside your product and work their work items, assignees and due dates there, with no per-customer code on your side.
- Handle the part that actually costs time: every team configures its own fields, statuses and workflow stages. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Google Tasks update is not your on-call problem.
- One integration serves your product and your agents. The same governed Google Tasks connection powers in-product features and gives AI agents scoped, audited access, so you keep work items in step with what happens in your product without wiring it twice.

AWS Simple Storage ServiceGoogle Tasks integration FAQ
How do I add a Google Tasks integration to my product?
Enable the Google Tasks connector in your fastn dashboard, then let each customer authenticate their own Google Tasks account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Google Tasks client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Google Tasks account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Google Tasks account and only ever sees their own work items, assignees and due dates. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Google Tasks integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent lists what is overdue across a customer's task lists and proposes an order to work them in.
Who maintains the Google Tasks integration?
fastn does. When Google Tasks changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can my product create and update work in Google Tasks automatically?
Yes. Items can be created, updated, assigned and transitioned from your product, and changes made in Google Tasks can trigger your workflows in return.
Does it adapt to each team's own Google Tasks setup?
Yes. However a team has configured Google Tasks, whether that is custom fields, statuses and workflow stages or its own calendars and working hours, those are mapped per customer, so an unusual setup works without custom code from you.
What can I build with the Google Tasks integration?
A common starting point: have each person authorise their own account, so a task your product files turns up in the list they genuinely check. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Google Tasks integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Google Tasks does not change your per-connector cost. You can start free with 3 connected accounts.
