Payment with Braintree retrieving data from vault

Question

I first created a customer with the help of API, when a customer created successfully then it returned me customerId, with the help of customerId I created a credit card.

// for creating user
gateway->customer()->create([
        'firstName' => $firstName,
        'lastName' => $lastName,
        'company' => $company,
        'email' => $email,
        'phone' => $phone,
        'fax' => $fax,
        'website' => $website
        ]);

//for creating card
$result = $this->gateway->creditCard()->create([
        'customerId' => $customerId,
        'number' => $number,
        'expirationDate' => $expirationDate,
        'cvv' => $cvv

After saving card in vault successfully it gives me a token In order to retrive data of card I did this:

$result = $this->gateway->creditCard()->find($token);

and it returned me the card detail, Now I want to perform payment with this card detail or token(as I am confused). previously I successfully done payment with drop in UI but I want to use vault this time

_{Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support.}

Now that you have the payment method token, you can pass that value as a parameter to the Transaction Sale API Call in order to complete a transaction with the saved payment method as opposed to a payment method nonce, which represents a single use payment method.

Example

$result = $gateway->transaction()->sale(
  [
    'paymentMethodToken' => 'the_payment_method_token',
    'amount' => '100.00'
  ]
);
