# GET /tasks changes: lang parameter was removed

Todoist API deprecated GET /tasks*, query parameter lang without giving a shutdown date yet.

The Todoist API deprecated and removed the lang query parameter on GET /tasks* calls without specifying a shutdown date. Requests relying on this parameter now fail. This removal directly affects calls made to GET /tasks* that include the lang query parameter.

## What to use instead

Use /api/v1/tasks/filter instead.

- API: Todoist API (api.todoist.com)
- Kind: Endpoint removal
- Takes effect: no date given yet
- Calls after that day: fail
- Calls it hits: `GET /tasks*`, `query parameter lang`
- Source: [Changelog](https://developer.todoist.com/api/v1/)
- Verified: October 27, 2026, against Todoist API's own pages
- Page: https://www.okapi.bot/providers/todoist-api/breaking-changes/get-tasks-changes-lang-parameter-was-removed/

## Todoist API's words

> The filter and lang parameters were removed: A new dedicated endpoint has been created specifically for filtering tasks: /api/v1/tasks/filter .
