# Resource Server Settings

Each Data Provider instance must be linked to a **Resource Server** — your API that exposes customer and product data.

Configuration is managed in the [**Console → Settings → Resource Server**](https://console.fiskil.com/data-holder/settings/resource-server).
Settings are applied per instance (staging, production, or additional environments).

***

## What You Configure

* **Base URL**
  The public HTTPS URL of your Resource Server. This must be accessible from Fiskil.

* **JWKS URL**
  The JWKS endpoint used to validate Fiskil [Authentication](/docs/get-started/authentication) JWTs.
  * You retrieve your isntance's public key from this URL

* **Firewall Allow-Lists (optional)**
  Restrict inbound traffic to requests originating from Fiskil IPs visible in the Resource Server menu.

***

## Best Practices

* Always use **distinct Resource Server URLs** for staging and production.
* Use firewall allow-lists for production environments.
