garminconnect 0.3.0

Python 3 API wrapper for Garmin Connect

Python: Garmin Connect

Note: Garmin has made significant changes to their authentication and API infrastructure. The old garth-based OAuth/cookie login no longer works. This library now authenticates using the same mobile SSO flow as the official Garmin Connect Android app, obtaining native DI OAuth Bearer tokens. Saved tokens are stored in a new format (garmin_tokens.json) — a fresh login is required after upgrading. All existing API methods remain unchanged — no code changes needed on your end, except when you store/handle tokens in your own project.

The Garmin Connect API library comes with two examples:

• example.py - Simple getting-started example showing authentication, token storage, and basic API calls
• demo.py - Comprehensive demo providing access to 130+ API methods organized into 13 categories for easy navigation

📦 Installation

Install from PyPI:

pip install --upgrade garminconnect curl_cffi

Run demo software (recommended)

python3 -m venv .venv --copies
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install pdm
pdm install --group :example

# Run the simple example
python3 ./example.py

# Run the comprehensive demo
python3 ./demo.py

🛠️ Development

Set up a development environment for contributing:

Note: This project uses PDM for modern Python dependency management and task automation. All development tasks are configured as PDM scripts in pyproject.toml. The Python interpreter is automatically configured to use .venv/bin/python when you create the virtual environment.

Environment Setup:

⚠️ Important: On externally-managed Python environments (like Debian/Ubuntu), you must create a virtual environment before installing PDM to avoid system package conflicts.

# 1. Create and activate a virtual environment
python3 -m venv .venv --copies
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# 2. Install PDM (Python Dependency Manager)
pip install pdm

# 3. Install all development dependencies
pdm install --group :all

# 4. Install optional tools for enhanced development experience
pip install "black[jupyter]" codespell pre-commit

# 5. Setup pre-commit hooks (optional)
pre-commit install --install-hooks

Alternative for System-wide PDM Installation:

# Install PDM via pipx (recommended for system-wide tools)
python3 -m pip install --user pipx
pipx install pdm

# Then proceed with project setup
pdm install --group :all

Available 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 errors (install codespell if needed)
pdm run test        # Run test suite
pdm run testcov     # Run tests with coverage report
pdm run all         # Run all checks
pdm run clean      # Clean build artifacts and cache files
pdm run build      # Build package for distribution
pdm run publish    # Build and publish to PyPI

View all available commands:

pdm run --list     # Display all available PDM scripts

Code Quality Workflow:

# Before making changes
pdm run lint       # Check current code quality

# After making changes
pdm run format     # Auto-format your code
pdm run lint       # Verify code quality
pdm run codespell  # Check spelling
pdm run test       # Run tests to ensure nothing broke

Run these commands before submitting PRs to ensure code quality standards.

🔐 Authentication

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

How it works:

1. 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.
2. 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.
3. 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

Prerequisites:

Run example.py once to create saved tokens in ~/.garminconnect.

# Install development dependencies
pdm install --group :all

Run Tests:

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
