Twilio SMS

Use this node to send SMS messages via the Twilio messaging service — for example, alerting a field technician’s mobile when a device alarm is raised, or sending an automated status update to a manager’s phone number stored in device metadata.

Configuration

Number From — required. Twilio sender phone number in E.164 format (e.g., +19995550123). Supports templatization.
Numbers To — required. Comma-separated recipient phone numbers. Supports templatization.
Account SID — required. Twilio account identifier.
Account Token — required. Twilio authentication token.

The message content is taken from the incoming message data (outer quotes and \n escape sequences are handled automatically).

Message processing algorithm

Resolve sender and recipient phone numbers from the configuration templates.
Send an SMS to each resolved recipient using the Twilio API with the incoming message data as the body.
Route via Success on delivery. Message data and metadata are not modified.
Route via Failure on unexpected error.

Output connections

Connection	Condition
`Success`	SMS sent to all recipients successfully.
`Failure`	Invalid credentials, Twilio API error, or unexpected error.
