From stripe.js details:
Card details:
The first argument to createToken is a JavaScript object containing credit card data entered by the user. It should contain the following required members:
number: card number as a string without any separators (e.g., "4242424242424242")
exp_month: two digit number representing the card's expiration month (e.g., 12)
exp_year: two or four digit number representing the card's expiration year (e.g., 2017)
(The expiration date can also be passed as a single string.)
cvc: optional, but we highly recommend you provide it to help prevent fraud. This is the card's security code, as a string (e.g., "123").
The following fields are entirely optional and cannot result in a token creation failure:
name: cardholder name
address_line1: billing address line 1
address_line2: billing address line 2
address_city: billing address city
address_state: billing address state
address_zip: billing postal code as a string (e.g., "94301")
address_country: billing address country
}
