Order Processing with REST APIs Tutorial

Step 6. Prepare for checkout

Now that all the items have been added to the cart, we can prepare the order for checkout . This process includes the following steps:

  • Estimate shipping costs
  • Set shipping and billing information

Estimate shipping costs

Magento calculates shipping costs for each shipping method that can be applied to the order. In this tutorial, the flatrate ($5 per item) and tablerate shipping methods are active.

Endpoint

POST http://<host>/rest/default/V1/carts/mine/estimate-shipping-methods

Headers

      "region": "New York",
      "region_id": 43,
      "region_code": "NY",
      "country_id": "US",
      "street": [
        "123 Oak Ave"

      "telephone": "(512) 555-1111",
      "same_as_billing": 1
  }
}

Response

Note that the cost for the flatrate shipping method is $15. The Sprite Yoga Companion Kit bundled product counts as one item. The Advanced Pilates & Yoga item does not have a shipping charge because the customer downloads this item.

]

Set shipping and billing information

In this call, you specify the shipping and billing addresses, as well as the selected carrier_code and method_code. Since the Table Rate shipping method costs only $5, the customer selected this option.

Magento returns a list of payment options and calculates the order totals.

If you tried this call on your own, and the value of the shipping_amount parameter is 0, then you did not deactivate the “Spend $50 or more - shipping is free!” cart price rule. See Deactivate a cart price rule for details.
