# WhatsApp Supported Features

## Ads that click to WhatsApp

Chat Flow now supports the [Ads that Click to WhatsApp](https://clickatell.gitbook.io/whatsapp-user-guide/channel-capabilities/ads-that-click-to-whatsapp) feature so that it can receive and store additional data in the session and make it available as [session variables](https://clickatell.gitbook.io/flow/variable-management-1#a-ds-that-click-to-whatsapp).

* **Source URL:** The Meta URL that leads to the ad or post clicked by the end-user (i.e., the source URL of the ad/post on Facebook).
* **Source ID**: The Meta ID for the ad or post that was clicked by the end-user.
* **Source Type:** The source type will be either an ad or a post.
* **Headline:** The headline of the ad/post that was clicked by the end-user.
* **Content:** The content of the ad/post that was clicked by the end-user.

## URL Preview

When a URL is sent to an end-user on WhatsApp via Chat Flow, it will now include a preview of the URL as shown below (2). Previously, only the URL was shown without a preview (1). The URL preview is also shown when [previewing your flow](https://clickatell.gitbook.io/flow/workflow-management/using-the-previewer) in the emulator.
