Shopify (API Key)

🚀 Quickstart

🚨 API gotchas

Starting January 1, 2026, you can no longer create legacy custom apps. We recommend using Shopify (OAuth) instead. This won’t impact any existing apps.

Create an integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Shopify API Key.

Authorize Shopify (API Key)

Go to Connections -> Add Test Connection -> Authorize, then enter your Shopify (API Key) credentials. Later, you’ll let your users do the same directly from your app.

Call the Shopify API

Let’s make your first request to the Shopify API (fetch a list of customers). Replace the placeholders below with your secret key, integration ID, and connection ID:

cURL
Node

curl "https://api.nango.dev/proxy/admin/api/2025-01/customers.json?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: '/admin/api/2025-01/customers.json',
    params: {
      limit: 10
    },
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(JSON.stringify(res.data, null, 2));

Or fetch credentials dynamically via the Node SDK or API.

✅ You’re connected! Check the Logs tab in Nango to inspect requests.

Next step: Embed the auth flow in your app to let your users connect their Shopify stores.
