# How to create Click-to-WhatsApp campaigns with Google Ads

Google lets you open WhatsApp directly from an ad using a **Message Asset**, a WhatsApp Business number attached to your ads. When someone taps the messaging call-to-action, WhatsApp opens with a pre-filled starter message and they land straight in a conversation with your agent.

{% hint style="warning" %}
**These conversations can't be attributed in Patagon AI.** Because there's no landing page, the Patagon AI tracking script never runs. No `gclid` and no UTMs are captured. The conversation still reaches your agent and gets qualified, but it appears as **untracked** in **Leads → Attribution**. If you need attribution, use [landing → WhatsApp campaigns](/en/marketing-and-attribution/google-campaigns/landing-to-whatsapp.md) instead.
{% endhint %}

So use Click-to-WhatsApp on Google when you want reach and volume and don't need source attribution in Patagon AI.

## Set up a Message Asset

Message assets are available on **Search** and **Performance Max** campaigns. You'll need a **WhatsApp Business account**, completed **advertiser verification**, and a starter message that complies with Google's policies.

1. In Google Ads, go to **Assets** and click **+**, then choose **Message asset**.
2. Pick the level — account, campaign, or ad group.
3. Select the **country** of your WhatsApp number and enter your **WhatsApp Business number**.
4. Add a **starter message**, a **call-to-action**, and a **description**.
5. Save. Once the asset is approved, Google automatically creates a **"Leads from Messages"** conversion goal and logs a **"conversation started"** conversion when someone initiates a chat.

## What you can measure

Only Google's native **"conversation started"** event — that a user opened a chat. There's no qualified-lead measurement, and nothing flows into Patagon AI's attribution for these campaigns. Optimize for conversations started, and switch to [landing → WhatsApp](/en/marketing-and-attribution/google-campaigns/landing-to-whatsapp.md) when you need to attribute and optimize for lead quality.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.patagon.ai/en/marketing-and-attribution/google-campaigns/click-to-whatsapp.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
