🚨 API gotchas

Create an integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Google Service Account.

Authorize Google Service Account

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

Call the Google API

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

cURL
Node

curl "https://api.nango.dev/proxy/calendar/v3/users/me/calendarList?maxResults=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: '/calendar/v3/users/me/calendarList',
    params: { maxResults: 10 },
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(res.data);

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 Google Service Account accounts.
