# Anonymous API access

Use your API key to access public WLL API endpoints without authentication.

Some White Label Loyalty (WLL) API endpoints can be accessed without user or admin authentication. These endpoints only require your tenant’s API key and are designed for displaying public-facing loyalty content.

This access level is called **anonymous** because it doesn’t require an access token.

***

## When to use anonymous access

Use anonymous access for public or pre-login experiences where no user identification is needed.

Examples include:

* Displaying available rewards on your website or app
* Listing venues participating in your loyalty program
* Previewing program features to encourage sign-up

***

## Authentication method

To authenticate anonymously, include your API key in the request header:

```
X-Api-Key: your-tenant-api-key
```

No `Authorization` header is required.

{% hint style="info" %}
Your API key can be found in the **Loyalty Console > Settings > Tenant** screen.
{% endhint %}

***

## Limitations

* Anonymous access only works for **read-only endpoints** marked as public in the API reference.
* You cannot perform any user-specific actions (e.g. view points, report events, view audience restricted rewards, redeem rewards).
* If authentication is required for a request and only an API key is provided, the request will be rejected with an authorization error.
