# Affinity (v2)

> Access the Affinity v2 API in 2 minutes 💨

> [tab] 🚀 Quickstart
>
> **1. Create an integration**
>
> In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Affinity (v2)*.
>
> **2. Authorize Affinity (v2)**
>
> Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then enter your Affinity API Key. Later, you'll let your users do the same directly from your app.
>
> **3. Call the Affinity (v2) API**
>
> Let's make your first request to the Affinity (v2) API (fetch current user information). 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/v2/auth/whoami" \
> >   -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: '/v2/auth/whoami',
> >   providerConfigKey: '<INTEGRATION-ID>',
> >   connectionId: '<CONNECTION-ID>'
> > });
> >
> > console.log(JSON.stringify(res.data, null, 2));
> > ```
>
> Or fetch credentials dynamically via 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).
