Walmart Marketplace - Nango Docs

🚀 Quickstart

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

Create the integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Walmart Marketplace.

Authorize Walmart Marketplace

Go to 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.

Call the Walmart Marketplace API

Let’s make your first request to the Walmart Marketplace API (list orders). Replace the placeholders below with your secret key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/v3/orders?limit=10" \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"

Install Nango’s backend SDK with npm i @nangohq/node. Then run:

import { Nango } from '@nangohq/node';

const nango = new Nango({ secretKey: '<NANGO-SECRET-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 or API.✅ You’re connected! Check the Logs tab in Nango to inspect requests.

Implement Nango in your app

Follow our quickstart to integrate Nango in your app.To obtain your own production 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 params option or the create connect session endpoint:

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