Apply multiple discounts on order create through rest API

[apopelka87]

Hi, we are currently migrating our e-commerce to Shopify and I'm working on historical order sync using REST API (the latest stable version) and NodeJS, some of our orders have up to 2 discounts applied but when I pass more than 1 discount code only the first one is applied to the order, for ex:

const shopifyOrder = new shopify.rest.Order({ session });

...

sOrder.discount_codes = [
          {
            code: "CODE_1",
            amount: "20",
            type: "fixed_amount",
          },
{
            code: "CODE_2",
            amount: "30",
            type: "fixed_amount",
          },
        ];

...

is it possible to create an order with more than one discount? thanks.

Having the same issue as you. Only the first discount code is applied when sending in an array of discount codes. 

Seems like a bug as the documentation clearly states we should be able to do this.

We're facing same problem, Let us know if you find a solution.

We are also experiencing this issue despite the documentation to the contrary (mentioned by Mattyonice).  We are trying to import historic orders and in some cases the order has both a line item discount and a shipping discount.  We are already grouping multiple line item discounts into one because of this issue, but we cannot group the shipping discount with the line item discount as line item discounts do not get applied to shipping values in Shopify.
