# Call to Action

> Sends a message with a button that opens an external URL

The **Call to Action** node sends a message with a button that, when tapped, opens a web page. It is ideal for directing the user to an external site: a store, a form, a payment page, or any URL.

## Webviews in WhatsApp

The URL opening behavior depends on the verification status of your Meta account:

* **Verified account**: The URL opens inside a webview embedded in WhatsApp, keeping the user within the app.
* **Unverified account**: The URL opens in the device's browser.
