This section explains how to create and manage orders for headless storefronts.
To successfully complete this section, you must first create a cart with a redirect URL. For instructions on how to create a cart, see the Carts article in this guide.
You can change a cart to a checkout by adding a billing address. To add a checkout billing address, send a request to the Add Checkout Billing Address endpoint. Your checkoutId will correspond with the cart ID returned by the Create a Cart endpoint. For an example request, see the End-to-End Guide: Headless Checkout Flow with REST Management APIs.
Now that you have transformed your headless cart into a checkout, you need to add a consignment with a shipping address, line items, and a shipping option. You can do so by adding and then updating a consignment. For an example request, see the End-to-End Guide: Headless Checkout Flow with REST Management APIs.
Now that you have added a billing address and a consignment to your checkout, you can create an order by sending a request to the Create an Order endpoint. When a new order is created by API, the order status is set to incomplete.
Depending on the shopper’s card-on-file authorization, you can use one of the following methods to process the payment.
GET request to the Get Accepted Payment Methods endpoint.Make a note of the access token id. This token is required in the subsequent order payment call to the Process Payment endpoint.
Authorization bearer token is the PAT ID returned by the Create Payment Access Token endpoint (step two). To learn more, see Payments API: Stored Cards.If a shopper does not have a payment method saved on file, you can process a payment using a credit card. There are two steps to this method:
Send a request to the Create Payment Access Token endpoint to get the payment access token that must be passed using the Authorization header to process the payment.
Send a request to the Process Payment endpoint. The headers to process a payment are different from the headers you normally send with a BigCommerce API. The Authorization bearer token is the PAT ID returned by the Create Payment Access Token endpoint (step one). To learn more, see Payments API: Credit Cards.
A successful transaction will return a success status. The order status is then automatically changed to Awaiting Fulfillment. If you get a different response, see Error Codes for troubleshooting.
