High Priority (Fix These First):

Fix MFA Response Handling:

gofunc (a GarthAuthenticator) authenticate(/ params */) (*Token, error) { // ... existing code ...

if resp.StatusCode == http.StatusPreconditionFailed {
    body, err := io.ReadAll(resp.Body)
    if err != nil {
        return nil, fmt.Errorf("failed to read MFA challenge: %w", err)
    }
    return a.handleMFA(ctx, username, password, mfaToken, string(body))
}

// ... rest of method

}

Create Complete Client Factory:

go// Add to garth.go func NewGarminClient(ctx context.Context, username, password, mfaToken string) (*GarminClient, error) { storage := NewMemoryStorage() auth := NewAuthenticator(ClientOptions{ Storage: storage, TokenURL: "https://connectapi.garmin.com/oauth-service/oauth/token", Timeout: 30 * time.Second, })

token, err := auth.Login(ctx, username, password, mfaToken)
if err != nil {
    return nil, err
}

transport := NewAuthTransport(auth.(*GarthAuthenticator), storage, nil)
httpClient := &http.Client{Transport: transport}
apiClient := NewAPIClient("https://connectapi.garmin.com", httpClient)

return &GarminClient{
    Activities: NewActivityService(apiClient),
    Profile:    NewProfileService(apiClient),
    Workouts:   NewWorkoutService(apiClient),
}, nil

}

Add Integration Test:

go//go:build integration // +build integration

func TestRealGarminFlow(t *testing.T) { client, err := NewGarminClient(ctx, username, password, "") require.NoError(t, err)

// Test actual API calls
profile, err := client.Profile.Get(ctx)
require.NoError(t, err)
require.NotEmpty(t, profile.UserID)

activities, err := client.Activities.List(ctx, ActivityListOptions{Limit: 5})
require.NoError(t, err)

}
