BigCommerce

Manage checkout operations and data on BigCommerce-hosted storefronts. To work with headless storefronts, use the [GraphQL Storefront API](/graphql-storefront/reference).

The REST Storefront API uses [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) headers for authentication, and therefore has no required scopes. You do not need to send any BigCommerce-specific tokens with your requests to these endpoints.
    
For info about authenticating BigCommerce APIs, see [Authentication and Example Requests](/docs/start/authentication#same-origin-cors-authentication).

Updates an existing consignment. An update is either one of the following:

1. Updates the consignment address and/or line items.
2. Selects a specific fulfillment option.

### Update the consignment address and line items
For this type of update, the payload is the same as when creating a new consignment.         Update each *Consignment* `shippingOptionId` (shipping address and line items) with the `availableShippingOption > id` from the POST `/consignment` response. 

**Note:**
Updating a consignment could invalidate the value for `selectedShippingOption` and `selectedPickupOption`.

### Select a specific fulfillment option
Before placing an order, each consignment must have a `selectedShippingOption` or a `selectedPickupOption`.

If the consignment already has a pick-up option selected and a shipping option is provided, the pick-up option will be deselected and the shipping option will be selected instead (and vice versa). The `PUT` request will fail if it contains a shipping option ID and a pickup option ID.

Required Fields:
* `shippingOptionId` or `pickupOptionId`
* `lineItems`
