The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such model

This instance publishes no model under that name. It may have been renamed, or no operation this installation serves uses it.

Back to the API reference

This reference may be out of date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 22:52 UTC.

API reference Models

SmsMessageCategory

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

Compliance category of an outbound SMS. Carried on `SmsMessage.Properties` (see `SmsMessageProperties`) so the send-time gate and the content / quiet-hours policy (`SmsContentPolicy`) can distinguish message classes.

Values

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.
