**How to set up a CTA URL**

2. Enter the relevant URL that will be triggered when the button is pressed. In the WhatsApp section, add the body text (header and footer are optional). &#x20;
   * To add media (images, videos or documents) as part of the header, add the publicly accessible URL to the **Menu Media Header Type** drop-down. If the link is not publicly accessible, the media will not display correctly.
