# Enrich Layer

> Integrate your application with the Enrich Layer API

## 🚀 Quickstart

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

**1. Create the integration**

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

**2. Authorize Enrich Layer**

Go to **Connections** -> *Add Test Connection* -> *Authorize*, then enter your Enrich Layer API key. Later, you'll let your users do the same directly from your app.

**3. Call the Enrich Layer API**

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

> [tab] cURL
>
> ```bash theme={null}
> curl "https://api.nango.dev/proxy/api/v2/credit-balance" \
>   -H "Authorization: Bearer <NANGO-API-KEY>" \
>   -H "Provider-Config-Key: <INTEGRATION-ID>" \
>   -H "Connection-Id: <CONNECTION-ID>"
> ```

> [tab] 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: '/api/v2/credit-balance',
>     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** tab in Nango to inspect requests.

**4. Implement Nango in your app**

> [!TIP]
>
> Not seeing the integration you need? [Build your own](https://nango.dev/docs/guides/functions/functions-guide.md) independently.

## API gotchas

* The v3 preview endpoints are served from `https://api.enrichlayer.com`, not the connection's base URL. Set `baseUrlOverride` to `https://api.enrichlayer.com` and call `/v3/...` endpoints; Nango keeps the connection's API key. See [Enrich Layer for agents](https://enrichlayer.com/agents.md).
