Overview
The SMS tools let a script text the contact during a call and read their replies, using the platform SMS stack with no integration to connect. Two tools are available:- Send to Contact — sends an SMS to the contact’s mobile mid-call, typically a confirmation near the end of the call. The message text supports variable substitution, so booking times, names, and links can be included.
- Read from Contact — reads the recent SMS exchange with the contact into a variable you nominate.
result and routes on true / Otherwise. Only a small set of sms variables is written as output — the plumbing variables the tools read as inputs (the message body and the composite’s opening, success, and failure lines) are not outputs and are not listed here.
Variables the SMS tools write
The Send to Contact tool writes{{sms.send_error_spoken}} (string) when a send fails; a successful send is signalled by the boolean result alone, and the tool writes nothing else to the sms namespace. The collected-email variable {{sms.email}} (string) is published by the SMS | Get Valid Email composite — which runs the whole round-trip (send, wait, read, extract, validate) — and you typically map it onward to a durable contact field such as {{contact.email}}. The Read from Contact tool on its own writes only the recent message exchange to a variable you nominate; it adds nothing to the sms namespace.
The
sms namespace is owned by the SMS tools — read from it in later steps, but never write into it yourself. For how variable references work across scripts and tools, see Variables.
