  • 🚨 API gotchas
1

Create an integration

In Nango (free signup), go to Integrations -> Configure New Integration -> Affinity (v2).
2

Authorize Affinity (v2)

Go to 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 secret key, integration ID, and connection ID:
  • cURL
  • Node
curl "https://api.nango.dev/proxy/v2/auth/whoami" \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>"
Or fetch credentials dynamically via the Node SDK or API.
✅ You’re connected! Check the Logs tab in Nango to inspect requests.
Next step: Embed the auth flow in your app to let your users connect their Affinity accounts.
