 | `get_journey_tracks` | The GPX tracks a journey's map draws, from the trips added to it: per track the place and trip it belongs to, its name, its kind, how many points it has and its length in km, plus `display_geometry`, the line thinned for drawing to at most 200 points per track and about 1000 for all tracks together, both ends always kept. Same journey access as the map. |
 | `get_journey_stats` | What a journey adds up to: distance travelled in metres, calendar days spanned, countries in visit order, the furthest point reached, and entry, photo and place counts. Entries switched off with `stats_excluded` count towards none of those and are listed under `excluded`. Pass `include_route` for the route itself, up to 400 stops with coordinates. |
 | `create_journey` | Create a new journey with title, optional subtitle, and an initial list of trip IDs. |
-| `update_journey` | Update a journey's title, subtitle, cover or status, and whether its entries offer a pros/cons list, a mood and a weather note (`show_verdict`, `show_mood`, `show_weather`). `status_override` sets the shown status by hand (`draft`, `live` or `completed`), `null` goes back to following the trip dates. `photo_location` lets an entry without a place take the position of its first geotagged photo. `auto_prepare_recordings` switches the preparation of its recorded days from Dawarich on or off. Owner only. |
