Returns a single SMS template: its body preview, category, the `variables` it expects (each with its accepted format), and the languages it is available in. Fetch a template before sending with it to see which `parameters` keys are required; an unknown reference returns a `404`. To browse the whole catalogue, use [List SMS templates](/docs/api/reference/list-sms-templates) instead. The template's `name` (for example `bird_otp_verification`) or its `smt_`-prefixed id. A reference starting with `smt_` resolves by id; anything else resolves by name. Unique identifier for the template. The template's stable handle. Pass it (or the id) as the template reference when sending. Human-readable description of what the template is for. Whether the template is a built-in Bird template (`system`) or one your workspace authored (`workspace`). Possible values: `system`, `workspace` Content classification applied to messages sent from this template. The template body in its default language, shown for preview. Variable placeholders appear inline (for example `{{ code }}`). The typed slots this template fills in from the values you supply when sending. The parameters key this slot is filled with. The value type this slot accepts. Open enum — treat any unrecognized value as a future type rather than an error. SMS templates use the typed slots (`code`, `amount`, …); email templates use `text`. Possible values (may grow over time): `code`, `ttl`, `count`, `ref`, `date`, `date_time`, `amount`, `currency`, `text` Whether the slot must be supplied when sending. Advisory for email templates, where a missing value renders as empty rather than rejecting the send. A human-readable description of the accepted values. The languages this template is available in, as BCP-47 tags. The template's lifecycle state. `active` means the template can be sent; every built-in Bird template is `active`. `draft` (being edited), `pending` (submitted for review), `approved` (passed review), and `rejected` (failed review) describe a workspace-authored template's authoring lifecycle; workspace-authored SMS templates are not available yet, so today every template is `active`. Possible values: `active`, `draft`, `pending`, `approved`, `rejected` The current editable draft version. Always null today: SMS templates are not yet versioned; present for parity with email templates. The currently published version, or null if the template has never been published.
