Send text

Use text for everyday replies and short updates while the customer can still receive free-form messages.

At a glance

Item	Detail
`type`	`text`
Channel support	Official and unofficial (matrix)
Body field	Prefer `content.body`; `content.text` (string or `{ "body": "..." }`) is accepted for compatibility
URL preview	Set preview behavior in `content` when the body includes a URL (provider-dependent)
Reply	Optional `content.reply_to.id` and `content.reply_to.participant`

Outside the 24-hour customer service window on official channels, use an approved template message for business-initiated outreach.
