Installation

Add the package to your Laravel project:

composer require filipac/withings-sdk

Configuration

Publish the configuration file:

php artisan vendor:publish --tag=withings-config

Add your Withings API credentials to your .env file:

WITHINGS_CLIENT_ID=your_client_id
WITHINGS_CLIENT_SECRET=your_client_secret
WITHINGS_ACCESS_TOKEN=your_access_token
WITHINGS_REFRESH_TOKEN=your_refresh_token

Usage

Basic Usage

use Filipac\Withings\Client\WithingsClient;
use Filipac\Withings\DataTransferObjects\Parameters\GetMeasuresParams;
use Filipac\Withings\Enums\MeasurementType;

// Create client with tokens
$client = new WithingsClient(
    accessToken: 'your_access_token',
    refreshToken: 'your_refresh_token',
    clientId: 'your_client_id',
    clientSecret: 'your_client_secret'
);

// 🎯 Type-safe enums eliminate magic strings
$params = new GetMeasuresParams(
    meastype: MeasurementType::WEIGHT, // Enum instead of magic number
    startdate: strtotime('2024-01-01'),
    enddate: strtotime('2024-12-31')
);

// Or use convenience factory methods
$params = GetMeasuresParams::forWeight(
    strtotime('2024-01-01'),
    strtotime('2024-12-31')
);

$measurementData = $client->measures()->getMeasures($params);

// 📦 Get Laravel Collections instead of arrays
$weightMeasurements = $measurementData->getWeightMeasurements(); // Collection
$latestWeight = $measurementData->getLatestMeasurement(MeasurementType::WEIGHT); // Single measurement

// Individual measurements are automatically converted to enums
$measurement = $weightMeasurements->first();
echo $measurement->type->getName(); // "Weight" (from enum)
echo $measurement->type->getUnit(); // "kg" (from enum)
echo $measurement->category?->getName(); // "Real measurement" (from enum)

Using the Facade (with Full IDE Completion)

use Filipac\Withings\Facades\Withings;
use Filipac\Withings\Enums\NotificationApplication;
use Filipac\Withings\Enums\MeasurementType;

// Full IDE autocompletion for all methods
$measurements = Withings::measures()->getWeight();

// Type-safe enum parameters with IDE hints
Withings::notifications()->subscribe(
    'https://your-webhook-url.com',
    NotificationApplication::WEIGHT,
    'My webhook comment'
);

// Access all services with complete method documentation
$heartData = Withings::heart()->getHeartRate();
$sleepSummary = Withings::sleep()->getSummary();
$userInfo = Withings::user()->getInfo();

The facade provides complete IDE autocompletion with:

• ✅ Method signatures with parameter types and return types
• ✅ Enum suggestions for type-safe parameters
• ✅ Documentation with usage examples
• ✅ Service method chaining with full completion at each step

🎯 Type-Safe Enums

All magic strings and numbers are replaced with type-safe enums:

use Filipac\Withings\Enums\{MeasurementType, MeasurementCategory, NotificationApplication, SleepField};

// ✅ Type-safe measurement types
$weight = MeasurementType::WEIGHT;
$bodyFat = MeasurementType::FAT_RATIO;
$heartRate = MeasurementType::HEART_RATE;

// ✅ Type-safe categories
$realMeasurement = MeasurementCategory::REAL;
$manualEntry = MeasurementCategory::MANUAL;

// ✅ Type-safe notification types
$weightNotifications = NotificationApplication::WEIGHT;

// ✅ Type-safe sleep fields
$sleepFields = [SleepField::DEEP_SLEEP_DURATION, SleepField::REM_SLEEP_DURATION];

// Get enum information
echo MeasurementType::WEIGHT->getName(); // "Weight"
echo MeasurementType::WEIGHT->getUnit(); // "kg"
echo MeasurementCategory::REAL->getDescription(); // "Real measurement taken by device"

📦 Laravel Collections

All data methods return Laravel Collections for powerful data manipulation:

$measurements = Withings::measures()->getWeight()->getMeasurements(); // Collection<Measurement>

// ✅ Fluent filtering and chaining
$recentWeights = $measurements
    ->filter(fn($m) => $m->type === MeasurementType::WEIGHT)
    ->sortByDesc('date')
    ->take(10)
    ->map(fn($m) => [
        'weight' => $m->getRealValue(),
        'date' => $m->getDateTime()->format('Y-m-d'),
        'category' => $m->category?->getName()
    ]);

// ✅ Powerful aggregations
$averageWeight = $measurements->avg('value') * pow(10, -3); // Convert to kg
$weightTrend = $measurements->pluck('value', 'date');

// ✅ Activity data with Collections
$activities = Withings::measures()->getActivity()->getActivities();
$totalSteps = $activities->sum('steps');
$averageDailySteps = $activities->groupBy('date')->map->sum('steps')->avg();

// ✅ Collection-specific methods
$activitiesByDate = $activities->getActivitiesGroupedByDate();
$weeklyAverage = $activities->getAverageDailySteps();

OAuth2 Flow

// Generate authorization URL
$authUrl = $client->oauth2()->getAuthorizationUrl(
    redirectUri: 'https://your-app.com/callback',
    state: 'optional-state',
    scopes: ['user.info', 'user.metrics']
);

// Exchange code for tokens
$tokens = $client->oauth2()->getAccessToken($code, $redirectUri);

// Refresh tokens
$refreshedTokens = $client->oauth2()->refreshToken();

// 🔧 Type-safe parameter creation with factory methods
$params = GetMeasuresParams::forBodyComposition(
    startdate: strtotime('-30 days'),
    enddate: time()
);

$measurementData = $client->measures()->getMeasures($params);

// 📦 Get Collection instead of array
$measurements = $measurementData->getMeasurements(); // Collection<Measurement>

// 🎯 Automatic enum conversion - no more magic numbers!
$measurement = $measurements->first();
echo $measurement->type; // MeasurementType::WEIGHT (enum)
echo $measurement->category; // MeasurementCategory::REAL (enum)

// ✅ Rich enum methods
echo $measurement->type->getName(); // "Weight"
echo $measurement->type->getUnit(); // "kg"
echo $measurement->category?->getDescription(); // "Real measurement taken by device"

// 📊 Collection-powered analysis

        'avg_value' => $monthlyData->avg('value'),
        'types' => $monthlyData->pluck('type')->unique()->map->getName()
    ]);

// 🎯 Type-safe filtering with enums
$weightMeasurements = $measurementData->getMeasurementsByType(MeasurementType::WEIGHT);
$latestWeight = $measurementData->getLatestMeasurement(MeasurementType::WEIGHT);

⚡ Error Handling

    echo "Status Code: " . $e->getCode();
}
