Magento 2 - Programatically Add Credit Card into Vault (BrainTree) - magento2

Question

I need to Add Credit Card details in to Vault Programmatically (BrainTree) in Magento 2.1.5
Basically what i want is After LoginIn there will be a separate section for Saved Cards . In that Customer is used to Add/edit/delete All his Credit card details.
the Below Code is used to list all the Credit Card saved by the Customer
use Magento\Vault\Api\PaymentTokenManagementInterface;
use Magento\Customer\Model\Session;
...
// Get the customer id (currently logged in user)
$customerId = $this->session->getCustomer()->getId();
// Card list
$cardList = $this->paymentTokenManagement->getListByCustomerId($customerId);
Now what i want is how to Add the Card Details to the Vault ?
Below is the Code to Add card in core php
$result = Braintree_Customer::create(array(
'firstName' => 'first name',
'lastName' => 'last name',
'company' => 'company',
'email' => 'xxxx#gmail.com',
'phone' => '1234567890',
'creditCard' => array(
'cardholderName' => 'xxx xxx',
'number' => '4000 0000 0000 0002 ',
'expirationMonth' => '10',
'expirationYear' => 2020,
'cvv' => '123',
'billingAddress' => array(
'firstName' => 'My First name',
'lastName' => 'My Last name'
)
)
));
But how can i do this same process in magento 2.
Thanks for the help

Answer 1

First, you have to create a payment token from the card data:
use Magento\Vault\Model\CreditCardTokenFactory;
...
$paymentToken = $this->creditCardTokenFactory->create();
$paymentToken->setExpiresAt('Y-m-d 00:00:00');
$paymentToken->setGatewayToken('card_112371K7-28BB-4O3X-CCG9-1034JHK27D88');
$paymentToken->setTokenDetails([
'type' => 'Visa',
'maskedCC' => '1111',
'expirationDate' => '06/2019'
]);
$paymentToken->setIsActive(true);
$paymentToken->setIsVisible(true);
$paymentToken->setPaymentMethodCode('your_payment_method_code');
$paymentToken->setCustomerId($customerId);
$paymentToken->setPublicHash($this->generatePublicHash($paymentToken));
Then you can save the payment token:
use Magento\Vault\Api\PaymentTokenRepositoryInterface;
...
$this->paymentTokenRepository->save($paymentToken);
This is just an example you can start with. In a real world situation, you would also want to check that the token doesn't already exist, an also try a payment authorisation on the card to make sure it's actually usable and valid.
In order to check if a payment token exists or not, you can use this:
use Magento\Vault\Api\PaymentTokenManagementInterface;
...
$this->paymentTokenManagement->getByPublicHash( $paymentToken->getPublicHash(), $paymentToken->getCustomerId() );
You can have a look at the core Magento 2 classes mentioned here to know more about the functions available for payment token handling.
Good luck!

Replace objectManager when use in projects
<?php
use Magento\Framework\Encryption\EncryptorInterface;
use Magento\TestFramework\Helper\Bootstrap;
use Magento\Vault\Model\AccountPaymentTokenFactory;
use Magento\Vault\Model\PaymentToken;
use Magento\Vault\Model\PaymentTokenRepository;
/** #var EncryptorInterface $encryptor */
$encryptor = $objectManager->get(EncryptorInterface::class);
/** #var PaymentToken $paymentToken */
$paymentToken = $objectManager->create(PaymentToken::class);
$paymentToken
->setCustomerId($customer->getId())
->setPaymentMethodCode('payflowpro')
->setType(AccountPaymentTokenFactory::TOKEN_TYPE_ACCOUNT)
->setGatewayToken('mx29vk')
->setPublicHash($encryptor->hash($customer->getId()))
->setTokenDetails(json_encode(['payerEmail' => 'john.doe#example.com']))
->setIsActive(true)
->setIsVisible(true)
->setExpiresAt(date('Y-m-d H:i:s', strtotime('+1 year')));
/** #var PaymentTokenRepository $tokenRepository */
$tokenRepository = $objectManager->create(PaymentTokenRepository::class);
$tokenRepository->save($paymentToken);
