How to add coupons or promotional codes to PaymentSheet?

Is your feature request related to a problem? Please describe. I am using the paymentIntents.create with a AWS Amplify GraphQL API to create a paymentIntent as described in the docs. Afterwards I initialize it with initPaymentSheet and subsequently present it using presentPaymentSheet. I would like to know how I would be able to add promotional codes linked to coupons/discounts similar to stripe.checkout.sessions.create

discounts: [{
    coupon: '{{COUPON_ID}}',
  }]

or allow_promotion_codes: true

Describe the solution you’d like I would like the paymentSheet to be initialized with a promotional code input field where customers can redeem their coupons/discounts.

Describe alternatives you’ve considered I have considered using the checkout and sessions API’s but found no way for the paymentIntent API.

I’m also looking to how to add allow_promotion_codes: true on the paymentIntent

Unfortunately this isn’t planned yet, you would need to handle this outside of the payment sheet flow (maybe making use of the customFlow: true parameter to separate out the “select payment method” and “confirm” steps)
