# Sending Documents via WhatsApp Flow

The **WhatsApp Flow** feature allows documents to be signed directly within WhatsApp, without the need to open external links. The entire signing process happens inside the conversation, offering greater convenience and a seamless experience for signers.

### How to use

To use the WhatsApp Flow signing feature, simply attach a file in **Markdown (.md)** format when creating the document. The contents of the file will be displayed directly in the WhatsApp conversation, allowing the signer to review the information and complete the signature process without leaving WhatsApp.

{% hint style="warning" %}
If the Markdown file is **not** attached, the document will be sent in the traditional format, and the signer will receive a **link** to access the signing platform outside WhatsApp.
{% endhint %}

For other signers who are **not configured** to sign via WhatsApp, the document will be rendered normally and the flow will follow the standard signing process.

### Supported Markdown tags

The WhatsApp API only supports the following **Markdown tags**:

```markdown
# Text Heading
## Text Subheading
Normal Paragraph

**bold**
*italic*
~~strikethrough~~

Unordered list does NOT accept sublevels

## 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.autentique.com.br/api/mutations/criando-um-documento/sending-documents-via-whatsapp-flow.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.
