Send SMS Notification requires three inputs.

Inputs

Input Field	Description	Required
Outbound SMS sender	The sender identity the message is sent from. Choose one of two options: • Outbound SMS number — a provisioned SMS-capable phone number. • Alpha sender ID — a provisioned alphanumeric sender ID. Both lists are populated from senders provisioned for Automated Notifications under Admin > Numbers.	Yes
Destination number	The Studio variable holding the recipient's phone number. Example: a variable populated from the Contact Lookup response, e.g. +15551234567.	Yes
SMS content	The text of the message to send. Supports Studio variables so the content can be personalized with data from the triggering event. Example: "Hi {{first_name}}, this is a reminder about your appointment on {{appointment_date}}."	Yes

Important: All three inputs must be non-empty at runtime. If the destination number cannot be resolved upstream, terminate the flow before this component rather than passing an empty value.
