Description
idrequired
string (uuid)
Values:Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
correlationIdrequired
string (uuid)
The platform correlation id for this message. Equal to `id`: there is
exactly one row per outbound message, so the correlation id is the document key. Surfaced under
its own name because that is what callers of the send API hold.

Values:Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
Unknown
No state recorded. Only ever seen on a malformed document.
GatewayBlocked
The send-time compliance gate refused the message (for example the recipient has opted out). No Twilio API call was made, so no carrier callback will ever follow. Distinct from GatewaySendFailed so a compliance block is auditable separately from a carrier fault.
GatewaySendFailed
The Twilio API rejected the create-message call. The message never entered the carrier network.
GatewaySent
Twilio accepted the message. Carrier callbacks (if a status callback URL was set) follow.
Queued
Carrier callback: the message is queued, accepted, scheduled, or sending.
Sent
Carrier callback: the message has been handed to the carrier.
Delivered
Carrier callback: the carrier confirmed delivery to the handset.
Undelivered
Carrier callback: the carrier could not deliver the message. Usually carries a Twilio error code.
Failed
Carrier callback: the message failed outright or was cancelled. Usually carries a Twilio error code.
isFailurerequired
boolean
Whether `status` means the message did not reach the handset.
Values:Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
twilioErrorCoderequired
integer (int32)

Transactional
Transactional message tied to a specific interaction the recipient initiated or expects (payment link, receipt, invoice, one-time passcode). This is the platform's default when a caller sets no category: every SMS sender wired today is transactional.
Marketing
Promotional / marketing message. Requires express marketing consent and is subject to the stricter content and timing policy. Callers sending marketing SMS must set this explicitly; it is never inferred.
Reminder
Recurring reminder in an ongoing program the recipient enrolled in (an overdue-invoice reminder series, a scheduled payment nudge). Not marketing, but recurring, so CTIA requires the opt-out instruction to ride on the message itself and TCPA timing applies.

Values:Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
