This SDK is generated automatically with JanePHP from the Yousign API.
It also provides a full object-oriented interface for all the endpoints, requests and responses of the Yousign API.
This library is built atop of PSR-7 and PSR-18. So you will need to install some implementations for those standard interfaces.
If no PSR-18 client or PSR-7 message factory is available yet in your project or you don't know or don't care which one to use, just install some default:
composer require symfony/http-client nyholm/psr7
You can now install the Yousign client:
composer require qdequippe/yousign-php-api
To create a client:
$client = \Qdequippe\Yousign\Api\Client::create();
$client->getSignatureRequests();
