# Content Security Policy (CSP)

If your website uses a Content Security Policy (CSP), you’ll need to allow Addressable’s scripts and images to load properly.

{% hint style="success" %}
**When Is This Needed**

Use this if:

* You have CSP headers configured on your site
* You see blocked requests in the browser console related to `adrsbl.io` or `adform.net` 
  {% endhint %}

### Required CSP Directives

To support Addressable and Adform tracking, update your CSP to include the following domains:

#### **For scripts:**

```
script-src
  https://*.adrsbl.io
  
script-src-elem
  https://*.adrsbl.io
  
connect-src
  https://*.adrsbl.io
```

#### **For images:**

```
img-src
  https://*.adrsbl.io
  https://*.adform.net;
```

These rules ensure the Addressable Pixel and Adform integrations function correctly without CSP-related errors.

{% hint style="warning" %}
If your policy uses a `default-src` directive with `'none'`, make sure to explicitly allow these sources in the appropriate directives above.
{% endhint %}
