# WhatsApp messaging

> Send and receive WhatsApp messages from a Meta-verified business number through SignalWire.

SignalWire's WhatsApp integration lets you send and receive WhatsApp messages from a
Meta-verified business number using the same platform, APIs, and routing you already use for
SMS, MMS, and voice. Inbound and outbound messages are handled through the same
[Messaging API](/docs/platform/messaging), so WhatsApp becomes one more channel
alongside the ones you already run, with no third-party middleware required.

The same business number can also take [WhatsApp calls](/docs/platform/voice/whatsapp).

## How it works

Customers reach your business through WhatsApp Ads or a Facebook call-to-action button, which
opens WhatsApp and starts a conversation with your Meta-verified business number. From there,
messages are handled programmatically like any other channel, with the
[Server SDKs](/docs/server-sdks), [SWML](/docs/swml), or [AI Agents](/docs/platform/ai).

## Prerequisites

To use WhatsApp messaging, you need a **Meta Business Account**.
