# Update an SMS template

`PATCH /api/v1/sms/templates/{id}`

Update an SMS template's `name`, `body` or `status`. A `published` template must have a message: publishing a blank `body`, or clearing the `body` of a published template, is refused with `422`. While an active SMS campaign uses a published template, editing its `body` or moving it back to `draft` is refused with `409`; unpublishing is also refused while a live automation sends it. Requires the `templates:write` capability.
