README

This package provides Amazon OAuth 2.0 support for the PHP League's OAuth 2.0 Client.

Installation

composer require marsaldev/oauth2-amazon

Amazon Setup

Before you can use this provider, you need to register your application with Amazon to get a Client ID and Client Secret:

Sign in to the Amazon Developer Console.
Go to Apps & Services → Login with Amazon and click Create a New Security Profile.
Fill in the Security Profile Name, Security Profile Description, and Consent Privacy Notice URL, then save.
Open the security profile you just created and go to the Web Settings tab: this is where you'll find your Client ID and Client Secret.
Still under Web Settings, click Edit and set:
- Allowed Origins — the origin(s) your application is served from (e.g. https://example.com)
- Allowed Return URLs — the exact redirect URI your app uses to receive the authorization code; this must match the redirectUri passed to the provider below
Use the Client ID, Client Secret, and redirect URI in your application as shown in Usage below.

Note: the profile scope is granted by default. The postal_code scope and the payments:* scopes used in the example below are tied to Amazon Pay and may require your security profile to be separately approved for those APIs before Amazon will grant them.

Usage

$amazonProvider = new \MichaelKaefer\OAuth2\Client\Provider\Amazon([
    'clientId'                => 'yourId',          // The client ID assigned to you by Amazon
    'clientSecret'            => 'yourSecret',      // The client password assigned to you by Amazon
    'redirectUri'             => 'yourRedirectUri'  // The return URL you specified for your app on Amazon
]);

// Get authorization code
if (!isset($_GET['code'])) {
    // Options are optional, defaults to 'profile' only
    $options = ['scope' => 'profile postal_code payments:widget payments:shipping_address payments:billing_address'];
    // Get authorization URL
    $authorizationUrl = $amazonProvider->getAuthorizationUrl($options);

    // Get state and store it to the session
    $_SESSION['oauth2state'] = $amazonProvider->getState();

    // Redirect user to authorization URL
    header('Location: ' . $authorizationUrl);
    exit;
// Check for errors
} elseif (empty($_GET['state']) || (isset($_SESSION['oauth2state']) && $_GET['state'] !== $_SESSION['oauth2state'])) {
    if (isset($_SESSION['oauth2state'])) {
        unset($_SESSION['oauth2state']);
    }
    exit('Invalid state');
} else {
    // Get access token
    try {
        $accessToken = $amazonProvider->getAccessToken(
            'authorization_code',
            [
                'code' => $_GET['code']
            ]
        );
    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
        exit($e->getMessage());
    }

    // Get resource owner
    try {
        $resourceOwner = $amazonProvider->getResourceOwner($accessToken);
    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
        exit($e->getMessage());
    }
        
    // Now you can store the results to session etc.
    $_SESSION['accessToken'] = $accessToken;
    $_SESSION['resourceOwner'] = $resourceOwner;
    
    var_dump(
        $resourceOwner->getId(),
        $resourceOwner->getName(),
        $resourceOwner->getPostalCode(),
        $resourceOwner->getEmail(),
        $resourceOwner->toArray()
    );
}
