Migration to API v9 and deprecation of v8 (to be removed on Oct 31, 2022)

[Lefteris Chatzimparmpas]

Hello Todoist API users and partners,

As v9 is the current stable version for the Sync API (you can learn more about it at developer.todoist.com), we are going to start the deprecation of its predecessor.

In case you have an application making API calls to any version less than v9, we strongly recommend you to migrate to v9 as soon as possible to avoid downtime after Oct 31, 2022.

Since today, we're returning a “warning” header for all API requests using a version less than v9:

$ curl -vs https://todoist.com/api/v8/sync -d token=$token |& grep warning
< warning: 119 - ”Deprecated API version. Will be removed on 2022-11-01”

Additionally, all other endpoints using a version less than v8 already return 410 GONE for a while now, and the same will happen to version v8 after the date mentioned.

Please contact us if you need any additional information about the API and how to migrate.

Stay safe and productive,
The Todoist Team

Hello Todoist API users and partners,

The previous message had an incorrect link for the migration guide to v9.  The correct one is:

We're sorry for the inconvenience.

Stay safe and productive,
