# WhatsApp
This section contains everything you need to know about the Zipchat x WhatsApp Integration.
### Why WhatsApp
WhatsApp is a service and marketing channel with incredible potential; it’s the most used messaging app in Europe, LATAM, India, and it’s growing fast in the United States
Main reasons to use WA:
* Open rate of marketing messages: 85%
* Click-through-rate: 15%
* Automatic collection of the customer’s Name, Surname and Phone Number
* 24 hours to keep the conversation going, while if someone texts you on your website, as soon as they close the browser you cannot reach to them
* You are always in your customers pocket, one conversation away
* Most importantly - customers EXPECT to speak with you on WA

## 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.zipchat.ai/channels/whatsapp.md?ask=&goal=
```
`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.
