This PR adds four methods for the Jet Lag Adviser: get_jetlag_trips, add_jetlag_trip, update_jetlag_trip and delete_jetlag_trip.

Endpoints

Method Call Response
get_jetlag_trips() GET /jetlag-service/jetlag/trip/all A list of trips
add_jetlag_trip(start_date, end_date, flights) POST /jetlag-service/jetlag/trip The trip, with tripId and a flightId on each flight
update_jetlag_trip(trip_id, start_date, end_date, flights) PUT /jetlag-service/jetlag/trip 204
delete_jetlag_trip(trip_id) DELETE /jetlag-service/jetlag/trip/{tripId} 204

Design

  • The methods fill userId from profile_id, in the same way as the menstrual writes fill userProfilePk.
  • A PUT replaces the whole trip. The method sets tripId on the trip and on each flight, the same as the web page does.
  • The web page also sends back dailyStatus on a PUT. Garmin calculates that field, and a PUT without it is accepted, so the method does not send it.
  • Garmin does not geocode a location. The location is free text, and the guidance comes from the UTC offset. So the flight validator requires an offset such as -07:00 and a local timestamp without an offset. A timezone name such as America/Los_Angeles, or a timestamp with an offset, will not work and is the easiest mistake to make.

Tests

  • Unit tests: 14 mocked tests in tests/test_garmin_unit.py cover the URLs, the bodies and the validation. The full suite passes, and so do ruff check, mypy, bandit and codespell. ruff format --check . reports only the existing code block at README.md:379, which also fails on master.

  • Live run: on a real account, the methods added, edited and deleted a trip. Garmin also accepted:

    • multi-leg trips, eastbound (PDX→MSP→ATL) and westbound (PDX→LAX→HNL);
    • a leg with no timezone change (PDX→SFO);
    • a trip in the past, which the web page does not allow;
    • a start date before the first flight.

    The docstring of add_jetlag_trip records these results.

Demo and README

The demo gets four Hydration & Wellness entries (l to o), and the README gets a Jet Lag Adviser example.

Summary by CodeRabbit

  • New Features
    • Added support for listing, creating, updating, and deleting Jet Lag Adviser trips, with checks for trip dates, flight details, and time zones.
    • Added demo options for managing trips, including a sample flight. During updates, leave date or flight inputs blank to retain existing values; deletion requires confirmation.
  • Documentation
    • Updated API coverage and documented trip requirements, update behavior, deletion, and actions that can change Garmin account data.

The library had no access to the Jet Lag Adviser. Garmin Connect lets a
user manage trips only in the app and on the web page at
/app/jet-lag-trips/manage-trips.

Add get_jetlag_trips, add_jetlag_trip, update_jetlag_trip and
delete_jetlag_trip. They use the endpoints that the web page calls,
under /jetlag-service/jetlag/trip. A browser capture gave the request
shapes. A DI-token session on connectapi gave the same results.

- The trip body takes userId from profile_id, the same way the
  menstrual writes fill userProfilePk.
- The PUT replaces the whole trip. The method sets tripId on the trip
  and on each flight, the same as the web page does.
- The web page also sends back dailyStatus on a PUT. Garmin calculates
  that field, and a live PUT without it was accepted, so the method
  does not send it.
- Garmin does not geocode a location. The flight validator requires
  a UTC offset such as "-07:00" and a local timestamp without an
  offset, because an IANA zone name or an aware timestamp is an easy
  mistake.

The demo gets four Hydration & Wellness entries. The README gets an
example and the new method counts.
Anchor the regex with ^ and $ like the other *_REGEX constants.
Live tests: a leg that changes no timezone, two-leg trips east
(PDX-MSP-ATL) and west (PDX-LAX-HNL), a trip in the past, and a start
date before the first flight. Garmin accepted all of them.
The web page names a trip after its first flight, and Garmin deletes
a trip by itself after the user has adjusted to home time.
The total now equals the sum of the category lines, which count the
demo menu entries. Upstream's 154+ was below that sum (157), so the
count had drifted before this branch.
Clarified the description of flight legs and updated the destination location format.

Merge Risk: 🔵 Low · up to 8bec9

Trip updates could report failure after succeeding for some empty responses, and unusual offset or trip-ID inputs can be mishandled. The remaining risks are bounded but warrant owner attention before merge.

Validate trip IDs without truncating them. Both methods convert trip_id with int() before validation. For example, 1.9 becomes 1, so an invalid ID can target a different trip.

  • garminconnect/__init__.py#L4422-L4422: reject fractional IDs before deleting a trip.
  • garminconnect/__init__.py#L4409-L4409: apply the same validation before replacing a trip.

No change in this PR. _validate_positive_integer(int(x), ...) is the pattern that the library uses for every ID, in about 26 places (delete_workout, delete_activity, get_workout_by_id, and others). If only these two methods changed, they would behave differently from the rest of the library. A trip ID also comes from get_jetlag_trips() as an int. A fix that refuses floats for all IDs is better as a separate PR.

@aaronspruit Thanks for the guidance. The supplied code confirms that these methods use the same ID-conversion pattern as delete_workout, delete_activity, and get_workout_by_id. A library-wide change is more consistent than changing only the Jet Lag Adviser methods.

No change is needed in this PR. The truncation concern remains valid as a follow-up. Would you like me to open an issue for consistent ID validation across the library?

Learning: In cyberjunky/python-garminconnect, Python ID-handling methods in garminconnect/__init__.py commonly use `_validate_positive_integer(int(x), ...)`, including Garmin.delete_workout, Garmin.delete_activity, and Garmin.get_workout_by_id. Rejecting float IDs should be handled consistently across the library in a separate change, rather than only in newly added Jet Lag Adviser methods.

Comment thread README.md Outdated
- UTC_OFFSET_REGEX accepts only -14:00 to +14:00, so +99:99 is refused.
- A timestamp without a time part is refused. fromisoformat() reads a
  date alone as midnight.
- The README example updates and deletes the trip that
  add_jetlag_trip() returned, not get_jetlag_trips()[0], which can be
  a different trip.
