Twilio

Twilio nodes let you send SMS and WhatsApp messages from your workflows.

Both nodes require a Twilio connection configured with your Account SID and Auth Token.

Nodes

Send SMS

Send an SMS (or MMS) message.

Field	Description	Notes
To	Recipient phone number in E.164 format	Required. Supports templates
From	Sender phone number	Optional (use Messaging Service SID instead)
Messaging Service SID	Twilio Messaging Service SID	Optional alternative to From
Message Body	Text content of the SMS	Required. Supports templates
Media URL	URL of media to attach (MMS)	Optional. Supports templates

Returns the Twilio message object including sid, status, and date_created.

Send WhatsApp

Send a WhatsApp message via the Twilio WhatsApp API. The whatsapp: prefix is added automatically to phone numbers.

Choose a Message Type to control which fields are shown:

Text Message

Send a free-form text message. Only works within the 24-hour conversation window (the recipient must have messaged you first).

Field	Description	Notes
To	Recipient phone number in E.164 format	Required. Supports templates
From	Sender WhatsApp number	Optional (use Messaging Service SID instead)
Messaging Service SID	Twilio Messaging Service SID	Optional alternative to From
Message Body	Text content of the message	Required. Supports templates
Media URL	URL of media to attach	Optional. Supports templates

Template Message

Send a pre-approved content template. Templates can initiate conversations outside the 24-hour window, making them ideal for notifications, alerts, and outbound messaging.

Field	Description	Notes
To	Recipient phone number in E.164 format	Required. Supports templates
From	Sender WhatsApp number	Optional (use Messaging Service SID instead)
Messaging Service SID	Twilio Messaging Service SID	Optional alternative to From
Content SID	Content Template SID (starts with HX)	Required. Supports templates
Content Variables (JSON)	JSON object mapping variable positions to values	Optional. Supports templates

Content variables example:

{"1": "John", "2": "Order #1234"}

TIP

Create and manage content templates in the Twilio Console under Content Editor, or via the Content API. Templates must be approved by Meta before use.

TIP

You must either provide a From number or a Messaging Service SID — one of the two is required by Twilio.

Streaming

Both nodes support streaming — when connected to an upstream list, each item triggers a separate message send.
