Messaging
A Connection node calls Twilio mid-decision with the credentials your own contract issued. Whatever comes back is data the rest of the flow can read, branch on, and keep in the decision's trace.
What a flow can call
/Accounts/$data.twilio_account_sid/Messages.jsonSends a text. To and From are E.164 — a leading plus, digits only.
/Accounts/$data.twilio_account_sid/Messages/$data.twilio_message_sid.jsonFetches one message by the SM… SID that Send an SMS returned at body.sid.
/Accounts/$data.twilio_account_sid/Messages.jsonMessage history, newest first. Filter with query parameters on the node — To, From, DateSent, PageSize — rather than pulling the whole account.
/Accounts/$data.twilio_account_sid/Messages/$data.twilio_message_sid.jsonDeletes the message record, including the text, from Twilio.

Where it sits in the decision
The call runs where the policy needs it — after the cheap checks that might make it unnecessary, before the rules that depend on it. Calls that do not depend on each other run together rather than in sequence.
Because it is part of the run, the response is part of the record. When someone asks why an applicant was declined months later, what Twilio returned at the time is in the trace, not re-fetched from a service whose answer has since changed.
