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

Installation

To install, use composer:

composer require sarhan/oauth2-docusign

Usage

Usage is the same as The League's OAuth client, using \Sarhan\OAuth2\Client\Provider\Docusign as the provider.

Authorization Code Flow

$provider = new \Sarhan\OAuth2\Client\Provider\Docusign([
    'clientId'          => '{docusign-integrator-key}',
    'clientSecret'      => '{docusign-integrator-key-secret}',
    'redirectUri'       => 'https://example.com/callback-url'
]);

if (!isset($_GET['code'])) {

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl();
    $_SESSION['oauth2state'] = $provider->getState();
    header('Location: ' . $authUrl);
    exit;

// Check given state against previously stored one to mitigate CSRF attack
} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {

    unset($_SESSION['oauth2state']);
    exit('Invalid state');

} else {

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

    // Optional: Now you have a token you can look up a users profile data
    try {

        // We got an access token, let's now get the user's details
        $user = $provider->getResourceOwner($token);

        // Use these details to create a new profile
        printf('Hello %s!', $user->getId());

    } catch (Exception $e) {

        // Failed to get user details
        exit('Oh dear...');
    }

    // Use this to interact with an API on the users behalf
    echo $token->getToken();
}

Refreshing a Token

$provider = new \Sarhan\OAuth2\Client\Provider\Docusign([
    'clientId'          => '{docusign-integrator-key}',
    'clientSecret'      => '{docusign-integrator-key-secret}',
    'redirectUri'       => 'https://example.com/callback-url'
]);

$token = $provider->getAccessToken('refresh_token', [
	'refresh_token' => '{refresh token}'
]);
