Order Module

In this section of the documentation, you will find resources to learn more about the Order Module and how to use it in your application.

Medusa has order related features available out-of-the-box through the Order Module. A module is a standalone package that provides features for a single domain. Each of Medusa's commerce features are placed in commerce modules, such as this Order Module.

Order Features#

• Order Management: Store and manage your orders to retrieve, create, cancel, and perform other operations.
• Draft Orders: Allow merchants to create orders on behalf of their customers as draft orders that later are transformed to regular orders.
• Apply Promotion Adjustments: Apply promotions or discounts to the order's items and shipping methods by adding adjustment lines that are factored into their subtotals.
• Apply Tax Lines: Apply tax lines to an order's line items and shipping methods.
• Returns, Edits, Exchanges, and Claims: Make changes to an order to edit, return, or exchange its items, with version-based control over the order's timeline.

How to Use the Order Module#

In your Medusa application, you build flows around commerce modules. A flow is built as a Workflow, which is a special function composed of a series of steps that guarantees data consistency and reliable roll-back mechanism.

You can build custom workflows and steps. You can also re-use Medusa's workflows and steps, which are provided by the @medusajs/medusa/core-flows package.

For example:

src/workflows/create-draft-order.ts
1import { 2  createWorkflow, 3  WorkflowResponse,4  createStep,5  StepResponse,6} from "@medusajs/framework/workflows-sdk"7import { Modules } from "@medusajs/framework/utils"8
9const createDraftOrderStep = createStep(10  "create-order",11  async ({}, { container }) => {12    const orderModuleService = container.resolve(Modules.ORDER)13
14    const draftOrder = await orderModuleService.createOrders({15      currency_code: "usd",16      items: [17        {18          title: "Shirt",19          quantity: 1,20          unit_price: 3000,21        },22      ],23      shipping_methods: [24        {25          name: "Express shipping",26          amount: 3000,27        },28      ],29      status: "draft",30    })31
32    return new StepResponse({ draftOrder }, draftOrder.id)33  },34  async (draftOrderId, { container }) => {35    if (!draftOrderId) {36      return37    }38    const orderModuleService = container.resolve(Modules.ORDER)39
40    await orderModuleService.deleteOrders([draftOrderId])41  }42)43
44export const createDraftOrderWorkflow = createWorkflow(45  "create-draft-order",46  () => {47    const { draftOrder } = createDraftOrderStep()48
49    return new WorkflowResponse({50      draftOrder,51    })52  }53)

You can then execute the workflow in your custom API routes, scheduled jobs, or subscribers:
