📦 Installation

Install from PyPI:

pip install --upgrade garminconnect curl_cffi

Run demo software (recommended)

Clone the repo, then:

python3 -m venv .venv --copies
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install -e ".[example]"

python3 ./example.py   # simple getting-started example
python3 ./demo.py      # comprehensive demo (130+ API methods)

🛠️ Development

This project uses PDM for dependency management and task automation.

⚠️ Important: Create a virtual environment first on externally-managed Python installs (Debian/Ubuntu) to avoid system package conflicts.

python3 -m venv .venv --copies
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install pdm
python -m pdm install --group :all
pre-commit install --install-hooks  # optional but recommended

Note: Using python -m pdm instead of pdm avoids PATH issues on some Windows setups where pip install pdm places the pdm executable outside the directories on PATH. Once pdm install has run, subsequent pdm run ... commands work normally because the venv's Scripts/ directory is on PATH while the venv is active.

Development commands:

pdm run format      # Auto-format code (isort, black, ruff --fix)
pdm run lint        # Check code quality (isort, ruff, black, mypy)
pdm run codespell   # Check spelling
pdm run test        # Run test suite
pdm run testcov     # Run tests with coverage report
pdm run all         # Run all checks (lint + codespell + pre-commit + test)
pdm run clean       # Clean build artifacts and cache files
pdm run build       # Build package for distribution
pdm run publish     # Build and publish to PyPI
pdm run --list      # Show all available commands

Run pdm run format && pdm run lint && pdm run test before submitting PRs.

🔐 Authentication

Authentication uses the same mobile SSO flow as the official Garmin Connect Android app. No browser is needed.

How it works:

First login: Authenticates via sso.garmin.com/mobile/api/login using the Android app's client ID. If MFA is required, a callback (prompt_mfa) prompts for the one-time code.
Token exchange: The service ticket is exchanged for DI OAuth Bearer tokens (access_token + refresh_token) via diauth.garmin.com. Tokens are stored at ~/.garminconnect/garmin_tokens.json.
Auto-refresh: Before each API request the library checks whether the DI token is about to expire and refreshes it automatically — no user interaction required.

Session lifetime:

DI tokens auto-refresh indefinitely as long as the refresh token remains valid.
A full re-login with credentials (and possibly MFA) is only needed if the refresh token itself expires or is revoked.

Token storage:

~/.garminconnect/garmin_tokens.json   # saved automatically, mode 0600

🧪 Testing

Run example.py once first to create saved tokens in ~/.garminconnect, then:

pdm run test        # Run all tests
pdm run testcov     # Run tests with coverage report

Optional: keep test tokens isolated

export GARMINTOKENS="$(mktemp -d)"
python3 ./example.py   # create a fresh token file for tests
pdm run test

Note: Tests use VCR cassettes to record/replay API responses. If tests fail with authentication errors, ensure valid tokens exist in ~/.garminconnect (run example.py first).

📦 Publishing

For package maintainers:

Setup PyPI credentials:

pip install twine
# Edit with your preferred editor, or create via here-doc:
# cat > ~/.pypirc <<'EOF'
# [pypi]
# username = __token__
# password = <PyPI_API_TOKEN>
# EOF

[pypi]
username = __token__
password = <PyPI_API_TOKEN>

Recommended: use environment variables and restrict file perms

chmod 600 ~/.pypirc
export TWINE_USERNAME="__token__"
export TWINE_PASSWORD="<PyPI_API_TOKEN>"

Publish new version:

pdm run publish    # Build and publish to PyPI

Alternative publishing steps:

pdm run build      # Build package only
pdm publish        # Publish pre-built package

Python Code Examples

import os
from datetime import date
from garminconnect import Garmin

# First run: logs in and saves tokens to ~/.garminconnect
# Subsequent runs: loads saved tokens and auto-refreshes
client = Garmin(
    os.getenv("EMAIL"),
    os.getenv("PASSWORD"),
    prompt_mfa=lambda: input("MFA code: "),
)
client.login("~/.garminconnect")

# Get today's stats
today = date.today().isoformat()
stats = client.get_stats(today)

# Get heart rate data
hr_data = client.get_heart_rates(today)
print(f"Resting HR: {hr_data.get('restingHeartRate', 'n/a')}")

Typed Workouts (Pydantic Models)

The library includes optional typed workout models for creating type-safe workout definitions:

pip install garminconnect[workout]

from garminconnect.workout import (
    RunningWorkout, WorkoutSegment,
    create_warmup_step, create_interval_step, create_cooldown_step,
    create_repeat_group,
)

# Create a structured running workout
workout = RunningWorkout(
    workoutName="Easy Run",
    estimatedDurationInSecs=1800,
    workoutSegments=[
        WorkoutSegment(
            segmentOrder=1,
            sportType={"sportTypeId": 1, "sportTypeKey": "running"},
            workoutSteps=[create_warmup_step(300.0)]
        )
    ]
)

# Upload and optionally schedule it
result = client.upload_running_workout(workout)
client.schedule_workout(result["workoutId"], "2026-03-20")

# Delete a workout or remove it from the calendar
client.delete_workout(workout_id)
client.unschedule_workout(scheduled_workout_id)

Available workout classes: RunningWorkout, CyclingWorkout, SwimmingWorkout, WalkingWorkout, HikingWorkout, MultiSportWorkout, FitnessEquipmentWorkout

Helper functions: create_warmup_step, create_interval_step, create_recovery_step, create_cooldown_step, create_repeat_group
