WhatsApp messaging
Send and receive WhatsApp messages through the SignalWire platform, currently in early-access alpha.
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, so WhatsApp becomes one more channel alongside the ones you already run, with no third-party middleware required.
WhatsApp on SignalWire is in early-access alpha, enabled per Space. Request access below to join the alpha.
What’s available today
During the alpha, the following is supported:
- Inbound and outbound messaging through the SignalWire Messaging API.
- Messaging from a Meta-verified business number that you connect through Meta’s embedded signup flow.
- Programmatic routing of inbound messages to your application, just like SMS and MMS.
Coming soon
The following capabilities are planned and are not yet available:
- Inbound and outbound WhatsApp voice calls, including routing to AI Agents.
- Messaging fallback to SMS/MMS when WhatsApp delivery fails.
- Message template management from the SignalWire Dashboard.
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, SWML, or AI Agents.
Prerequisites
To use WhatsApp messaging during the alpha, you need:
- A Meta Business Account.
- A SignalWire Space enabled for WhatsApp alpha access.
- To authorize the connection between Meta and SignalWire through the embedded signup flow.
Once connected, your registered business number can be used for inbound and outbound messaging and programmatic routing.
