This package provides Docusign OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-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

```php
$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

```php
$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}'
]);
```

## Vendor specific options

`sandbox`

when passed with `true` to the provider constructor, the provider will direct docuaign endpoint calls to docusign sandbox domain (account-d.docusign.com).

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

## Testing

```bash
$ ./vendor/bin/phpunit
```

or

```bash
$ composer test
```
