# Do I need separate provider apps and DNS per environment?

You **don't need a separate provider app or extra DNS records per** [**Terra environment**](https://docs.tryterra.co/health-and-fitness-api/integration-setup/understanding-terra-environments).

The same provider credentials work across testing, staging, and production, and users are connected in whichever environment initiated the auth.

If you do want separate provider apps per environment, **keep the same custom domain and append the provider app's client ID to the webhook path** (e.g. `/hooks/{provider}/push/{client_id}`). Users are then split per environment with distinct user IDs.
