# Autumn

> Integrate your application with the Autumn API

Autumn (useautumn.com) is a billing and subscription layer on top of Stripe: customers, plans, feature entitlements, usage tracking and billing events, all through one API.

## 🚀 Quickstart

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

**1. Create the integration**

In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Autumn*.

**2. Authorize Autumn**

Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Autumn* -> enter your secret API key and click *Authorize*. See the [connect guide](https://nango.dev/docs/api-integrations/autumn/connect) for how to obtain a key.

**3. Call the Autumn API**

Let's make your first request to the Autumn API (get the organization). Replace the placeholders below with your [Environment API key](https://nango.dev/docs/reference/backend/http-api/api-keys.md), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

**cURL**

```bash theme={null}
curl "https://api.nango.dev/proxy/v1/organization" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"
```

**Node**

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

```typescript theme={null}
import { Nango } from '@nangohq/node';

const nango = new Nango({ apiKey: '<NANGO-API-KEY>' });

const res = await nango.get({
    endpoint: '/v1/organization',
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>'
});

console.log(res.data);
```

Or fetch credentials with the [Node SDK](https://nango.dev/docs/reference/backend/backend-sdk/node.md#get-a-connection-with-credentials) or [API](https://nango.dev/docs/reference/backend/http-api/connections/get.md).

✅ You're connected! Check the [Logs](https://app.nango.dev/dev/logs) tab in Nango to inspect requests.

**4. Implement Nango in your app**

Follow our [quickstart](https://nango.dev/docs/getting-started/quickstart.md) to integrate Nango in your app.
