This guide is aimed at advanced users who have some experience with Spree API and Stripe. You also need to install Spree Stripe extension before.
If you’re using the standard Spree Storefront, then you can skip this tutorial as quick checkout is already built in.

​
Prerequisites

Assume that you have a cart made with line items in it already. Quick checkout works by handling 3 different events:
  • Address change
  • Shipping Method/Rate change
  • Confirmation
How you should handle them depends on your platform/language:

​
Checkout Flow

​
Address change

Here we need to send some basic information about the customer’s shipping address, and we should move the order to the delivery step (don’t forget to replace the placeholders with the customer’s data):

​
Shipping Method/Rate change

Here we need to send the selected shipping method to the backend and update the total in the payment element Endpoint documentation
Select shipping method
curl -X PATCH '<SHOP URL>/api/v2/storefront/checkout/select_shipping_method' \
  -H 'Authorization: Bearer <Token>' \
  -H 'Content-Type: application/json' \
  -d '{
    "shipping_method_id": <Shipping Method ID>
  }'
​
shipping_method_id
string
required
Shipping method ID of the selected shipping rate
Subsequently, update the payment element with a new total taken from the response’s total_minus_store_credits

​
Confirming the payment

Now you should make several more calls to the backend
Thereafter, you should confirm the payment intent using the Stripe library; this depends on your platform/language.
<PAYMENT INTENT ID> should be Spree’s internal payment intent ID, which you will receive when you create the payment intent. Do not confuse it with Stripe’s payment intent ID.
If you like to redirect the user to Spree’s order summary page, then set the return_url when confirming the payment intent to <SHOP URL>/stripe/payment_intents/<PAYMENT INTENT ID>. This will check if the payment intent is confirmed, move the order to the complete state, and redirect the user to the order summary. If you like to make the order summary page by yourself, then after confirming the payment intent in Stripe, make this request:
Confirm payment intent
curl -X POST <SHOP URL>/api/v2/storefront/stripe/payment_intents/<PAYMENT INTENT ID>/confirm \
  -H 'Authorization: Bearer <Token>'
Endpoint documentation This will also check if the payment intent is confirmed, and it will move the order to the complete state

​
User cancels the payment

If at any point, the user cancels the payment (closes the quick checkout sheet/modal), you will need to handle this event and clear the shipping and billing address from the order as these addresses will not be valid and if someones decides to use standard checkout it could lead to errors.
Reset order addresses
curl -X PATCH <SHOP URL>/api/v2/storefront/checkout \
  -H 'Authorization: Bearer <Token>' \
  -H 'Content-Type: application/json' \
  -d '{
    "order": {
      "ship_address_id": "CLEAR",
      "bill_address_id": "CLEAR"
    }
  }'
