# MillionVerifier

> Integrate your application with the MillionVerifier API

## Quickstart

Connect to MillionVerifier 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* -> *MillionVerifier*.

**2. Authorize MillionVerifier**

Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then enter your API key. Later, you'll let your users do the same directly from your app.

**3. Call the MillionVerifier API**

Let's make your first request to the MillionVerifier API. 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):

> [tab] cURL
>
> ```bash theme={null}
> curl "https://api.nango.dev/proxy/v3/credits" \
>   -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: '/v3/credits',
>     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 [Auth implementation guide](https://nango.dev/docs/guides/primitives/auth.md) to integrate Nango in your app.

> [!NOTE]
>
> This integration covers MillionVerifier's Single API (real-time email verification and credit balance), which shares one base URL and API key query parameter. The Bulk API runs on a separate host (`bulkapi.millionverifier.com`) with its own `key` query parameter and isn't covered by this integration.
