# Create Topic

> Creates a topic on a website. Topics group prompts for aggregate reporting; pass the returned `id` as `prompts[].topic_id` when creating prompts. Get-or-create by name: if an active topic with the same name already exists, the existing topic is returned with `created: false` instead of failing, so retries and re-imports are idempotent.
