## Handle card setup

`stripe.handleCardSetup(clientSecret: string, data?: object)`

*`handleCardSetup` has been renamed to [confirmCardSetup](#stripe_confirm_card_setup). In addition to the rename, we have slightly modified the arguments. These changes do not affect the behavior of the method. While we have no plans to ever remove support for `handleCardSetup`, we think the new name and arguments are easier to understand and better convey what the method is doing.*

Use `stripe.handleCardSetup(clientSecret, data)` to advance the `SetupIntent` towards completion when you are not gathering payment method information from an `Element`.

Call this variation when you have already attached a card to this `SetupIntent` or if you want to attach an existing card to it.

> Note that `stripe.handleCardSetup` may take several seconds to complete.
> During that time, you should disable your form from being resubmitted and show a waiting indicator like a spinner.
> If you receive an error result, you should be sure to show that error to the customer, re-enable the form, and hide the waiting indicator.
> 
> Additionally, `stripe.handleCardSetup` may trigger a [3D Secure](https://docs.stripe.com/payments/3d-secure.md) authentication challenge.
> This will be shown in a modal dialog and may be confusing for customers using assistive technologies like screen readers.
> You should make your form accessible by ensuring that success or error messages are clearly read out after this method completes.

  The [client secret](https://docs.stripe.com/api/setup_intents/object.md#setup_intent_object-client_secret) of the `SetupIntent`.

Only one of `payment_method_data` and `payment_method` is required.

      Use this parameter to supply additional data relevant to the payment method, such as billing details.
      - `billing_details`
        The [billing details](https://docs.stripe.com/api/payment_methods/create.md#create_payment_method-billing_details) associated with the card.
