Handle Card Setup

Handle card setup stripe.handleCardSetup(clientSecret: string, data?: object) handleCardSetup has been renamed to confirmCardSetup. 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 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. - clientSecret The client secret of the SetupIntent. - data Data to be sent with the request. - payment_method Use payment_method to specify an existing PaymentMethod to use for this payment.
