  Step 4: Setting Headers for Iframe Embedding
</h2>

<p>Configure the appropriate HTTP headers to ensure your widget works securely in an iframe. There are two primary headers to consider:</p>

<p><strong>Remove the X-Frame-Options Header</strong>: The X-Frame-Options header is deprecated but still widely respected by many browsers. To remove it, add the following configuration in an initializer:<br>
</p>

<pre class="brush:php;toolbar:false"># config/initializers/security_headers.rb
Rails.application.config.action_dispatch.default_headers.delete('X-Frame-Options')
