LolautruchePaylineBundle uses PaylineSDK in the background, and defines it as a service. Using the SDK to consume specific Payline services is as easy as getting the gateway 😄
// Inside a controller
/** @var \Lolautruche\PaylineBundle\Payline\Payline $paylineGateway */
$paylineGateway = $this->get('payline');
/** @var \Payline\PaylineSDK $paylineSDK */
$paylineSDK = $paylineGateway->getPaylineSDK();
$payineSDK->createWebWallet([/* */]);
