# Walmart Marketplace

> Integrate your application with the Walmart Marketplace API

## 🚀 Quickstart

Connect to Walmart Marketplace with Nango and see data flow in 2 minutes.

**1. Create the integration**

In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Walmart Marketplace*.

**2. Authorize Walmart Marketplace**

Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then sign in to Walmart Seller Center and grant access. Later, you'll let your sellers do the same directly from your app.

**3. Call the Walmart Marketplace API**

Let's make your first request to the Walmart Marketplace API (list orders). Replace the placeholders below with your [Environment API key](https://nango.dev/docs/reference/backend/http-api/api-keys.md), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

> [tab] cURL
>
> ```bash theme={null}
> curl "https://api.nango.dev/proxy/v3/orders?limit=10" \
>   -H "Authorization: Bearer <NANGO-API-KEY>" \
>   -H "Provider-Config-Key: <INTEGRATION-ID>" \
>   -H "Connection-Id: <CONNECTION-ID>"
> ```

> [tab] Node
>
> Install Nango's backend SDK with `npm i @nangohq/node`. Then run:
>
> ```typescript theme={null}
> import { Nango } from '@nangohq/node';
>
> const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });
>
> const res = await nango.get({
>     endpoint: '/v3/orders',
>     params: { limit: '10' },
>     providerConfigKey: '<INTEGRATION-ID>',
>     connectionId: '<CONNECTION-ID>'
> });
>
> console.log(res.data);
> ```

Or fetch credentials with the [Node SDK](https://nango.dev/docs/reference/backend/backend-sdk/node.md#get-a-connection-with-credentials) or [API](https://nango.dev/docs/reference/backend/http-api/connections/get.md).

✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.

**4. Implement Nango in your app**

Follow our [quickstart](https://nango.dev/docs/getting-started/quickstart.md) to integrate Nango in your app.

To obtain your own credentials, follow the setup guide linked below.

## ⚙️ Connection configuration

The `clientType` connection config field controls which Walmart marketplace your integration targets. It defaults to `seller` (US). Override it when creating connections for other markets:

| Value | Marketplace |
| - | - |
| `seller` | United States (default) |
| `seller-ca` | Canada |
| `seller-mx` | Mexico |

Pass it via the [frontend SDK](https://nango.dev/docs/reference/frontend/frontend-sdk.md) `params` option or the [create connect session](https://nango.dev/docs/reference/backend/http-api/connect/sessions/create.md) endpoint:

```typescript theme={null}
await nango.auth('walmart', '<CONNECTION-ID>', {
    params: { clientType: 'seller-ca' }
});
```
