Todoist
Add Todoist to your product for your customers, and give your AI agents governed access to it.
Todoist is where a lot of people keep the list they actually work from, which makes it a good place for your product to put something it wants a human to do. An embedded Todoist integration creates tasks in the projects and sections a person already uses, sets a due date, priority and labels, reads back what has been completed, and reacts when it has. Two details shape the build. Todoist is authorised per person rather than per company, so the connected account is an individual's own workspace and what your product can write is bounded by what that person granted. And recurring tasks do not simply close: completing one schedules the next occurrence, so a product that treats completion as an end state will misreport work that is still ongoing. fastn holds each person's token, refreshes it, and follows the API.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each user connect their own Todoist account so work your product generates lands in the list they already open every morning.
Create a task in the right project and section with a due date, priority and labels, rather than dropping everything into an inbox.
React when a task is completed so the step your product owns continues without anybody reporting it back manually.
Handle recurring tasks correctly, treating a completion as the start of the next occurrence rather than the end of the work.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads what is due today for one connected person and tells them what is worth doing first.
An agent creates or reschedules a task within the permissions that person granted, with the project it wrote to logged.
An agent finds tasks with no due date that have been sitting untouched and offers to close or reschedule them.
Example prompt
What is overdue in my Todoist projects, and which of those items has been rescheduled more than twice?
Set up Todoist in 4 steps
- 01Enable the Todoist connector in your fastn dashboard.
- 02Have each user authorise their own Todoist account, since access is granted per person rather than per company.
- 03Map the project, section, label and due date fields your product uses, then enable the actions and triggers you need.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Todoist integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Todoist integration without building it. Your customers connect their own Todoist 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 Todoist update is not your on-call problem.
- One integration serves your product and your agents. The same governed Todoist 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 ServiceTodoist integration FAQ
How do I add a Todoist integration to my product?
Enable the Todoist connector in your fastn dashboard, then let each customer authenticate their own Todoist account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Todoist client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Todoist account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Todoist 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 Todoist 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 reads what is due today for one connected person and tells them what is worth doing first.
Who maintains the Todoist integration?
fastn does. When Todoist 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 Todoist automatically?
Yes. Items can be created, updated, assigned and transitioned from your product, and changes made in Todoist can trigger your workflows in return.
Does it adapt to each team's own Todoist setup?
Yes. However a team has configured Todoist, 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 Todoist integration?
A common starting point: let each user connect their own Todoist account so work your product generates lands in the list they already open every morning. 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 Todoist integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Todoist does not change your per-connector cost. You can start free with 3 connected accounts.
