# Display modals after purchase

The new [`paymentSessionModal`](https://shopify.dev/docs/api/payments-apps/unstable/mutations/paymentSessionModal) mutation raises a modal that will be displayed to the buyer after purchase. This modal uses provided data to display additional info to buyers. For example, you could show a QR Code that a buyer can scan, or render message telling buyers to complete an action on an external device.
