# SMTP2GO

> Integrate your application with the SMTP2GO API

## 🚀 Quickstart

Connect to SMTP2GO 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* -> *SMTP2GO*.

**2. Authorize SMTP2GO**

Go to **Connections** -> *Add Test Connection* -> *Authorize*, then choose your region and enter your SMTP2GO API key. Later, you'll let your users do the same directly from your app.

**3. Call the SMTP2GO API**

Let's make your first request to the SMTP2GO API to list the endpoints your API key can use. 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 -X POST "https://api.nango.dev/proxy/v3/api_keys/permissions" \
>   -H "Authorization: Bearer <NANGO-API-KEY>" \
>   -H "Provider-Config-Key: <INTEGRATION-ID>" \
>   -H "Connection-Id: <CONNECTION-ID>" \
>   -H "Content-Type: application/json" \
>   -d '{}'
> ```

> [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.post({
>     endpoint: '/v3/api_keys/permissions',
>     data: {},
>     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**

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