This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-22 22:09 UTC.

API reference Messaging

SMS Log: gets the delivery record for one outbound message by its correlation id.

GET /api/twilio/sms-log/by-correlation/{correlationId} deprecated

Requires: Twilio.SmsLog.View, merchant scope.

This is the lookup a sending feature uses to reflect a delivery outcome on its own record: it holds the correlation id returned by the send, and asks here whether the message was delivered, blocked by the compliance gate, or failed at the carrier. The tenant and merchant ids must match the message's owning scope, and the caller's own scope is enforced on top. Returns no content when no record exists, which includes a message whose row has aged out of the 30-day retention window.

Field Type Description
id required 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.
correlationId required 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.
toPhoneNumberMasked required string Recipient reduced to its last four digits (for example `•••••••4567`). nullable
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.
fromPhoneNumberMasked required string Sending number reduced to its last four digits, when the send used a from-number. nullable
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.
messagingServiceSid required string The Messaging Service SID the send routed through, when one was configured. nullable
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.
messageSid required string Twilio's message SID, once the API accepted the message. Null for blocked / failed sends. nullable
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.
status required SmsDeliveryStatus SmsDeliveryStatus Where the message currently sits in its lifecycle.
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.
isFailure required 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.
twilioErrorCode required integer (int32) Twilio numeric error code from the failing send or callback, when one was reported. nullable
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.
failureCode required string Platform error code explaining a gateway-side refusal (for example a compliance block). nullable
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.
bodyLength required integer (int32) Message length in characters. The body itself is never stored or returned. nullable
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.
category required SmsMessageCategory SmsMessageCategory Declared message category.
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.
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.
timestamp required string (date-time) When the send was attempted (UTC).
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.
lastStatusAt required string (date-time) When the most recent carrier callback was applied (UTC). Null until the first one lands. nullable
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.
tenantId required string (uuid) Tenant the message was sent under. nullable
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.
merchantId required string (uuid) Merchant the message belongs to. nullable
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.

429 The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.
