Create an integration

In Nango (free signup), go to Integrations -> Configure New Integration -> SAP Business One.

Authorize SAP Business One

Go to Connections -> Add Test Connection -> Authorize, then enter your SAP Business One credentials. Later, you’ll let your users do the same directly from your app.

Call the SAP Business One API

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

cURL
Node

curl "https://api.nango.dev/proxy/b1s/v2/Users" \
  -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({
  // https://help.sap.com/doc/056f69366b5345a386bb8149f1700c19/10.0/en-US/Service%20Layer%20API%20Reference.html
  endpoint: '/b1s/v2/Users',
  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 SAP Business One accounts.
