# Custom Order Display ID

In this guide, you'll learn how to customize the display ID of orders in Medusa.

This feature is available since [Medusa v2.12.0](https://github.com/medusajs/medusa/releases/tag/v2.12.0).

## Default Display ID

By default, Medusa stores the display ID of orders in the `display_id` property of the [Order data model](https://docs.medusajs.com/resources/references/order/models/Order). The display ID is a serial integer that starts at 1 and increments with each new order.

For example:

```json
{
  "id": "order_123",
  "display_id": 1,
  // other properties...
}
```

***

## Custom Display ID

In some cases, you might want to use a custom display ID for orders. This is useful for integrating with external systems or providing a more user-friendly order identifier.

The `Order` data model has a `custom_display_id` property that stores a custom display ID you generate.

You can define the logic for generating this ID in the `generateCustomDisplayId` module option set in `medusa-config.ts`.

For example:

```ts title="medusa-config.ts"
// other imports...
import { Modules } from "@medusajs/framework/utils"
import { OrderTypes, Context } from "@medusajs/framework/types"

module.exports = defineConfig({
  modules: [
    {
      key: Modules.ORDER,
      options: {
        generateCustomDisplayId: async function (
          order: OrderTypes.CreateOrderDTO,
          sharedContext: Context
        ): Promise<string> {
          // Return your custom display ID
          return `${order.email}-${Date.now()}`
        },
      },
    },
    // other modules...
  ],
  // other configurations...
})
```

In the example above, the `generateCustomDisplayId` function generates a custom display ID by combining the order's email with the current timestamp.

You can implement any logic to generate a unique and meaningful display ID for your orders.

***

## View Custom Display ID in Medusa Admin

By default, Medusa Admin displays the `display_id` in the table on the Orders page. To view the custom display ID in the table, you can enable the `view_configurations` experimental feature.

To enable this feature, add the following to `medusa-config.ts`:

```ts title="medusa-config.ts"
module.exports = defineConfig({
  // other configurations...
  featureFlags: {
    view_configurations: true,
  },
})
```

This enables the feature's flag.

Next, run the necessary migrations:

```bash
npx medusa db:migrate
```

Then, start the Medusa application:

```bash
npm run dev
```

Finally, customize the Order view in Medusa Admin to display the `custom_display_id` property.

***

## Search Orders by Display ID

The `display_id` and `custom_display_id` properties are searchable fields of the `Order` data model. So, you can search orders by either display ID without any customizations.

The Order Module also defines database indexes on both properties. The index on `custom_display_id` is unique, so each custom display ID must be unique among orders that aren't deleted.

### Search in Medusa Admin

The search box on the Orders page of Medusa Admin searches the order's searchable fields, including `display_id` and `custom_display_id`. So, you can enter an order's display ID or custom display ID in the search box to find it.

### Search with the Admin API

To search orders by display ID with the [List Orders API route](https://docs.medusajs.com/api/admin/orders/list-orders), pass the display ID or custom display ID in the `q` query parameter.

For example, using the [JS SDK](https://docs.medusajs.com/resources/js-sdk):

```ts
const { orders } = await sdk.admin.order.list({
  q: "ORD-1234",
})
```

The `q` parameter performs a case-insensitive partial match on the order's searchable fields, which also include the email and the shipping and billing addresses. For example, searching for `12` returns orders whose display ID is `12`, `120`, or `1234`.

The List Orders API route doesn't accept `display_id` or `custom_display_id` as dedicated filter parameters. Use the `q` parameter instead.

### Filter with Query in Customizations

To retrieve an order by its exact display ID or custom display ID in your customizations, such as an API route or workflow step, use [Query](https://docs.medusajs.com/learn/fundamentals/query) and pass the property in `filters`.

For example:

```ts
const { data: orders } = await query.graph({
  entity: "order",
  fields: ["id", "display_id", "custom_display_id"],
  filters: {
    custom_display_id: "ORD-1234",
  },
})
```
