// @title Vikunja API
// @description This is the documentation for the [Vikunja](http://vikunja.io) API. Vikunja is a cross-plattform To-do-application with a lot of features, such as sharing lists with users or teams. <!-- ReDoc-Inject: <security-definitions> -->

// @description # Pagination
// @description Every endpoint capable of pagination will return two headers:
// @description * `x-pagination-total-pages`: The total number of available pages for this request
// @description * `x-pagination-result-count`: The number of items returned for this request.
// @description # Rights
// @description All endpoints which return a single item (list, task, namespace, etc.) - no array - will also return a `x-max-right` header with the max right the user has on this item as an int where `0` is `Read Only`, `1` is `Read & Write` and `2` is `Admin`.
// @description This can be used to show or hide ui elements based on the rights the user has.
// @description # Authorization
// @description **JWT-Auth:** Main authorization method, used for most of the requests. Needs `Authorization: Bearer <jwt-token>`-header to authenticate successfully.
// @description
// @description **BasicAuth:** Only used when requesting tasks via caldav.
