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](!docs!/learn/fundamentals/modules) 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.

<Note>

Learn more about why modules are isolated in [this documentation](!docs!/learn/fundamentals/modules/isolation).

</Note>

## Order Features

- [Order Management](./concepts/page.mdx): 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](./promotion-adjustments/page.mdx): 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](./tax-lines/page.mdx): Apply tax lines to an order's line items and shipping methods.
- [Returns](./return/page.mdx), [Edits](./edit/page.mdx), [Exchanges](./exchange/page.mdx), and [Claims](./claim/page.mdx): Make [changes](./order-change/page.mdx) to an order to edit, return, or exchange its items, with [version-based control](./order-versioning/page.mdx) 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](!docs!/learn/fundamentals/workflows), 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:

export const highlights = [
  ["12", "Modules.ORDER", "Resolve the module in a step."]
]

```ts title="src/workflows/create-draft-order.ts" highlights={highlights}
import { 
  createWorkflow, 
  WorkflowResponse,
  createStep,
  StepResponse,
} from "@medusajs/framework/workflows-sdk"
import { Modules } from "@medusajs/framework/utils"

const createDraftOrderStep = createStep(
  "create-order",
  async ({}, { container }) => {
    const orderModuleService = container.resolve(Modules.ORDER)

    const draftOrder = await orderModuleService.createOrders({
      currency_code: "usd",
      items: [
        {
          title: "Shirt",
          quantity: 1,
          unit_price: 3000,
        },
      ],
      shipping_methods: [
        {
          name: "Express shipping",
          amount: 3000,
        },
      ],
      status: "draft",
    })

    return new StepResponse({ draftOrder }, draftOrder.id)
  },
  async (draftOrderId, { container }) => {
    if (!draftOrderId) {
      return
    }
    const orderModuleService = container.resolve(Modules.ORDER)

    await orderModuleService.deleteOrders([draftOrderId])
  }
)

export const createDraftOrderWorkflow = createWorkflow(
  "create-draft-order",
  () => {
    const { draftOrder } = createDraftOrderStep()

    return new WorkflowResponse({
      draftOrder,
    })
  }
)
```

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

<CodeTabs group="resource-types">
  <CodeTab label="API Route" value="api-route">
    
```ts title="src/api/workflow/route.ts" highlights={[["11"], ["12"]]} collapsibleLines="1-6" expandButtonLabel="Show Imports"
import type {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"
import { createDraftOrderWorkflow } from "../../workflows/create-draft-order"

export async function GET(
  req: MedusaRequest,
  res: MedusaResponse
) {
  const { result } = await createDraftOrderWorkflow(req.scope)
    .run()

  res.send(result)
}
```

  </CodeTab>
  <CodeTab label="Subscriber" value="subscriber">
    
```ts title="src/subscribers/user-created.ts" highlights={[["11"], ["12"]]} collapsibleLines="1-6" expandButtonLabel="Show Imports"
import {
  type SubscriberConfig,
  type SubscriberArgs,
} from "@medusajs/framework"
import { createDraftOrderWorkflow } from "../workflows/create-draft-order"

export default async function handleUserCreated({
  event: { data },
  container,
}: SubscriberArgs<{ id: string }>) {
  const { result } = await createDraftOrderWorkflow(container)
    .run()

  console.log(result)
}

export const config: SubscriberConfig = {
  event: "user.created",
}
```

  </CodeTab>
  <CodeTab label="Scheduled Job" value="scheduled-job">
    
```ts title="src/jobs/run-daily.ts" highlights={[["7"], ["8"]]}
import { MedusaContainer } from "@medusajs/framework/types"
import { createDraftOrderWorkflow } from "../workflows/create-draft-order"

export default async function myCustomJob(
  container: MedusaContainer
) {
  const { result } = await createDraftOrderWorkflow(container)
    .run()

  console.log(result)
}

export const config = {
  name: "run-once-a-day",
  schedule: `0 0 * * *`,
}
```

  </CodeTab>
</CodeTabs>
