BigChange - Nango Docs

🚀 Quickstart

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

Create the integration

In Nango (free signup), go to Integrations -> Configure New Integration -> BigChange. Enter your BigChange Partner API Client ID and Client Secret.

Authorize BigChange

Go to Connections -> Add Test Connection -> Authorize, then enter the customer’s numeric Customer ID. BigChange uses OAuth 2.0 Client Credentials, so there is no user-facing sign-in screen — the connection is created as soon as the Customer ID is submitted. Later, you’ll let your users do the same directly from your app.

Call the BigChange API

Let’s make your first request to the BigChange 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/v1/users?page-number=1&page-size=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: '/v1/users?page-number=1&page-size=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. Nango automatically injects the customer-id header on every proxy call from the connection’s customer_id field.
