Garmin Connect CLI

This skill provides access to Garmin Connect health and fitness data through the gc CLI.

Setup

1. Install via Homebrew tap:

brew tap voydz/homebrew-tap
    brew install garmin-cli

1. Authentication:

gc login --email user@example.com --password secret
    # With MFA:
    gc login --email user@example.com --password secret --mfa 123456

1. Verify connection:

gc status

Date Shortcuts

Most commands accept a date shortcut as first argument:

• today — current date
• yesterday — previous date
• week — last 7 days (returns a date range)
• month — last 30 days (returns a date range)
• YYYY-MM-DD — specific date

For command groups with subcommands (activities, body, stress, heart, menstrual),

use --date on the parent command to avoid argument conflicts.

Alternatively use --date, --start/--end flags.

Output

All data commands support:

• --format json for machine-readable output (default: table)
• --output FILE to write to a file

Always use --format json when parsing output programmatically.

## Workouts Steps JSON Schema (`--steps`)

`--steps` expects a JSON array of step objects. Each step can be shorthand or Garmin-shaped.

Shorthand step example:

json

{"type":"interval","duration":1200,"target":"hr_zone:2"}

Supported shorthand fields:
- `type`: `warmup`, `interval`, `recovery`, `cooldown`, `rest`, `repeat`
- `duration`: seconds (implies `endCondition` = `time`)
- `target`: `hr_zone:2`, `power_zone:3`, `pace_zone:4`, `heart_rate:150`, `power:220`, `cadence:90`, `no_target`

Garmin-shaped fields (optional):
- `stepType`: `{"stepTypeKey":"warmup"}` (or any Garmin stepType object)
- `stepOrder`: integer
- `endCondition`: `{"conditionTypeKey":"time|distance|calories|heart_rate|cadence|power|iterations"}`
- `endConditionValue`: number
- `targetType`: `{"workoutTargetTypeKey":"no.target|heart.rate|power|speed|cadence|open|heart.rate.zone|power.zone|pace.zone"}`
- `targetValue`: number

For advanced Garmin payloads (repeat groups, nested steps, etc.), prefer `--file` with the full Garmin schema.

# Menstrual Cycle
gc menstrual --date today
gc menstrual calendar --start DATE --end DATE
gc menstrual pregnancy

# Raw API
gc api /biometric-service/biometric/latestFunctionalThresholdPower/CYCLING
gc api --method POST --body '{"foo":"bar"}' /some/endpoint

Examples

Get today's health summary as JSON:

gc health today --format json

Get last week's steps as JSON for analysis:

gc steps week --format json

Find the user's most recent run:

gc activities --limit 5 --type running --format json

Call a raw Garmin Connect API endpoint:

gc api /biometric-service/biometric/latestFunctionalThresholdPower/CYCLING
gc api --method POST --body '{"foo":"bar"}' /some/endpoint

Get detailed info about a specific activity:

gc activities get 12345678 --format json

Download an activity as GPX:

gc activities download 12345678 --format gpx -o run.gpx

Check training readiness and HRV:

gc metrics training-readiness today --format json
gc metrics hrv today --format json

Get sleep and body battery for yesterday:

gc sleep yesterday --format json
gc battery yesterday --format json

Workout creation (concise)

• Prefer --file with a Garmin-shaped JSON payload.
• Get a valid payload by exporting an existing workout:

gc workouts get WORKOUT_ID --format json > workout.json

• If using flags, --steps can be the exact workoutSteps JSON array from the API

or a shorthand array with type, duration (seconds), and optional target (e.g. hr_zone:2).

• --sport-id is optional when --sport is provided; the CLI resolves the id from activity types.

Garmin workout shape (minimal example):

{
  "workoutName": "Zone 2 Ride",
  "sportType": {
    "sportTypeKey": "cycling",
    "sportTypeId": 17
  },
  "workoutSegments": [
    {
      "segmentOrder": 1,
      "sportType": {
        "sportTypeKey": "cycling",
        "sportTypeId": 17
      },
      "workoutSteps": [
        {
          "stepOrder": 1,
          "stepType": { "stepTypeKey": "warmup" },
          "endCondition": { "conditionTypeKey": "time" },
          "endConditionValue": 600
        },
        {
          "stepOrder": 2,
          "stepType": { "stepTypeKey": "interval" },
          "endCondition": { "conditionTypeKey": "time" },
          "endConditionValue": 3600
        }
      ]
    }
  ]
}

Example creations:

# Create from file (recommended)
gc workouts create --file workout.json

# Create with flags using exact Garmin steps JSON
gc workouts create \
  --name "Zone 2 Ride" \
  --sport cycling \
  --sport-id 17 \
  --steps '[{"stepOrder":1,"stepType":{"stepTypeKey":"warmup"},"endCondition":{"conditionTypeKey":"time"},"endConditionValue":600},{"stepOrder":2,"stepType":{"stepTypeKey":"interval"},"endCondition":{"conditionTypeKey":"time"},"endConditionValue":3600}]'

How to discover format and valid values for workout creation:

• Sport type keys/ids (used in sportType):
• gc activities types --format json
• Workout step/target enums are not hardcoded in the CLI.
• Export an existing workout and reuse the exact values:

gc workouts get WORKOUT_ID --format json

• Use the returned stepType, endCondition, and targetType fields verbatim.

List devices and get solar data:

gc devices --format json
gc devices solar DEVICE_ID today --format json
