# Contact Info Request

> Ask the user to share their WhatsApp phone number

Sends a message with WhatsApp's **Share Contact Info** button. When the user taps it, WhatsApp shares their
phone number in the chat. This is useful for users who show a username instead of their phone number.

<Note>
  This message can only be sent within the 24-hour customer service window. Outside that window, use a
  template with the **Share Contact Info** button instead. It is not available for every WhatsApp connection:
  if your app's connection doesn't support it, the request returns `400`.
</Note>

## Request

Use `type` as `interactive` and set `interactive.type` to `request_contact_info`.

### Field types

* `to`: string (required) — phone number or WhatsApp user ID
* `type`: string = `interactive` (required)
* `interactive`: object (required)
* `interactive.type`: string = `request_contact_info` (required)
* `interactive.body`: object (required)
* `interactive.body.text`: string (required)

### Field behavior and limits

* `interactive.body.text` is required, max 1024 characters.
* The button text can't be customized: WhatsApp shows it in the user's language.
* `interactive.action` is set automatically; any value you send is ignored.

```json theme={null}
{
  "to": "+573001112233",
  "type": "interactive",
  "interactive": {
    "type": "request_contact_info",
    "body": {
      "text": "To keep helping you, please share your phone number."
    }
  }
}
```

## The user's reply

When the user taps the button, their reply arrives in the conversation as a **contacts** message with the
shared phone number. If the user shares someone else's contact card instead, it arrives as a regular contacts
message.
