**How to set up a CTA URL**
1. Insert a new [Rich Link](/flow/user-facing-nodes/display-nodes/rich-link.md) node, ensuring that the **URL** is the selected option. The title of the CTA will be the button text.
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).
* 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.
