# Render an AI Template

Render a template for a specific contact and sender profile. The simplest usage is to pass an existing template `uuid` along with `lead_uuid` and `sender_profile_uuid` — the saved template configuration is used.
For ad-hoc rendering without a saved template, pass the full set of fields (subject, body, type, llm_uuid, llm_config, prompt, enable_validation, enable_fallback, settings).
