Braintree payment gateway - Get customer information

Question

I am using the Braintree payment gateway in my web application. I am wondering if I can get user information from it.

I can't save the card details, it's not allowed. But if I need to run another transaction for the same user, can I get his information from Braintree itself and auto-fill in the card details?

One of the main advantages of payment gateways like Braintree is that they tokenize credit card information without you having to be exposed to it.

Basically, you use Braintree.js to encrypt the card information in the browser so your server never sees it.

Then, you pass that encrypted information on to Braintree. In return, you get a token like "xg67ba" which you can later use to charge the same card again:

result = Braintree::Transaction.sale(
  :amount => "100.00",
  :customer => {
    :first_name => "Dan",
    :last_name => "Smith"
  },
  :credit_card => {
    :number => "encryped_credit_card_number",
    :expiration_date => "encryped_expiration_date",
    :cvv => "encrypted_cvv"
  },
  :options => {
    :store_in_vault => true
  }
)

result.transaction.customer_details.id
#=> e.g. "131866"
result.transaction.credit_card_details.token
#=> e.g. "f6j8"

So the next time, it would look like:

result = Braintree::Transaction.sale(
  :amount => "10.00",
  :customer_id => "131866",
  :credit_card => {:cvv => 'encrypted_cvv'}
)

Every credit card is associated with a customer, and so if you just want to charge a customer's only / default card, you can just provide the customer id. Getting the cvv from the customer again (which no one is ever allowed to store) is recommended but not required.

Once you have customer Id, you can get the Customer details by using following PHP-code.

$customerId = 67222186;  
   try{
       $result = Braintree_Customer::find($customerId); 
      echo $result->id; echo "\n";
      echo $result->firstName; echo "\n";
      echo $result->lastName; echo "\n";
      echo $result->email; echo "\n";
      echo $result->phone; echo "\n";
   }  catch (Exception $e){
    echo $e->getMessage();
  }
