Twilio
Send SMS or WhatsApp messages from a live call, via your organization's own Twilio account.
This is the Twilio connector — agent actions for sending SMS/WhatsApp messages mid-call. It's unrelated to Twilio as a telephony provider, which is about placing and receiving phone calls. You can use one, both, or neither independently.
The Twilio connector lets your voice agents send an SMS or WhatsApp message directly from a conversation, using your organization's own Twilio account.
Connect it
Twilio uses your Account SID and Auth Token, not OAuth.
- Go to /connectors and click Connect on Twilio.
- Enter your Account SID and Auth Token, found in your Twilio Console.
- Enter a SMS From Number and/or a WhatsApp From Number — whichever channel(s) you plan to use. These are often different numbers: a number provisioned for SMS is frequently not usable for WhatsApp and vice versa (for example, Twilio's shared WhatsApp Sandbox number sends WhatsApp messages fine but is rejected outright for plain SMS). If you only fill in SMS From Number,
send_whatsapp_messagewill fall back to using it — useful if you're testing with a single sandbox number that happens to work for both. - Click Connect.
Actions
| Action | Description | Parameters |
|---|---|---|
send_sms | Send an SMS text message via Twilio. | to_number (required, E.164), message_body (required) |
send_whatsapp_message | Send a WhatsApp message via Twilio's WhatsApp API. | to_number (required, E.164), message_body (required) |
Attach these to a workflow node like any other tool — see Tools for how tool attachment and invocation work.
Example
A booking agent calls send_sms to text a confirmation of the appointment time to the caller's number before ending the call. A support agent calls send_whatsapp_message to follow up on WhatsApp instead, if that's the channel the caller reached out on.
If you already connected Twilio before this connector supported WhatsApp, reconnect (re-enter your credentials and click Connect again) to pick up the new send_whatsapp_message action — connecting always re-provisions any tools for newly available actions.
