Non-English texts in Stripe possible?

Question

Successfully integrating Stripe into my online shop, I completely failed to get information on whether/how to configure Stripe to return error messages in German instead of English.

So my question is:

Is there a way to have localized error messages when using the client-side API "https://js.stripe.com/v2"?

Update 2014-05-03

I've asked the same question on Twitter and one of their staff (I guess) told me that this is currently not possible and on their TODO list.

Answer 1

NOTE

The text is not production ready. It's just the developer text. Some errors shouldn't be showed to the user. If I have some better texts I will re edit this. If someone has the time to do so, feel free to edit.

If you would like to provide their english text:

Answer 2

For further reference:

While you can't use human messages on stripe errors to be displayed directly on localized pages, you can take advantage of response.error.code to provide your own translations.

var errorMessages = {
  incorrect_number: "The card number is incorrect.",
  invalid_number: "The card number is not a valid credit card number.",
  invalid_expiry_month: "The card's expiration month is invalid.",
  invalid_expiry_year: "The card's expiration year is invalid.",
  invalid_cvc: "The card's security code is invalid.",
  expired_card: "The card has expired.",
  incorrect_cvc: "The card's security code is incorrect.",
  incorrect_zip: "The card's zip code failed validation.",
  card_declined: "The card was declined.",
  missing: "There is no card on a customer that is being charged.",
  processing_error: "An error occurred while processing the card.",
  rate_limit:  "An error occurred due to requests hitting the API too quickly. Please let us know if you're consistently running into this error."
};


function stripeHandler( status, response ){
  if ( response.error && response.error.type == 'card_error' ){
    $( '.errors' ).text( errorMessages[ response.error.code ] );
  }

  else {
    // do other stuff (and handle api/request errors)
  }
}

The list of codes is documented here (currently, right column, in the "codes" section).
