Requirements

The following versions of PHP are supported.

• PHP 5.6
• PHP 7.0
• PHP 7.1
• HHVM

Installation

To install, use composer:

composer require waytohealth/oauth2-withings

Usage

Authorization Code Grant

use waytohealth\OAuth2\Client\Provider\Withings;

$provider = new Withings([
    'clientId'          => '{withings-oauth2-client-id}',
    'clientSecret'      => '{withings-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url'
]);

// Fetch the authorization URL from the provider; this returns the
// urlAuthorize option and generates and applies any necessary parameters
// (e.g. state).
$authorizationUrl = $provider->getAuthorizationUrl($options);

// Try to get an access token using the authorization code grant.
$accessToken = $provider->getAccessToken('authorization_code', $options);

// Add subscription
$subscriptionUrl = sprintf('https://wbsapi.withings.net/notify?action=subscribe&access_token=%s&callbackurl=%s&appli=%s&comment=Way_To_Health',
    $accessToken,
    $params['callbackurl'],
    $params['appli']
);
$subscriptionRequest = $provider->getAuthenticatedRequest('GET', $subscriptionUrl, $accessToken, $options);
$provider->getParsedResponse($request);

// Get data
$request = $provider->getAuthenticatedRequest('GET', $url, $accessToken, $options);
$data = $provider->getParsedResponse($request);

Refreshing a Token

Once your application is authorized, you can refresh an expired token using a refresh token rather than going through the entire process of obtaining a brand new token. To do so, simply reuse this refresh token from your data store to request a refresh.

$provider = new waytohealth\OAuth2\Client\Provider\Withings([
    'clientId'          => '{withings-oauth2-client-id}',
    'clientSecret'      => '{withings-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url'
]);

$existingAccessToken = getAccessTokenFromYourDataStore();

if ($existingAccessToken->hasExpired()) {
    $newAccessToken = $provider->getAccessToken('refresh_token', [
        'refresh_token' => $existingAccessToken->getRefreshToken()
    ]);

    // Purge old access token and store new access token to your data store.
}
