Back on 2023/08/14 we introduced a new authentication system that allows for both Track and Plan to have common user accounts.

We are announcing the deprecation of Toggl Track's API v8. Calls to previous /api/v8/* endpoints, documented in the now archived [toggl_api_docs repository][toggl_api_docs], will cease to work in about six months. They should be replaced by their /api/v9/* counterparts documented in the [Docs][docs] section of this site.

This blog-like [Changes][changes] part of the documentation is where all the relevant changes made to the Toggl Track API will be published. Backwards-incompatible changes and deprecation notices will be informed in advance, allowing API clients to plan their migration accordingly.
