# DELETE Delete a font

Removes the font and returns a deletion receipt: a snapshot of exactly what was removed, so the caller can verify and report the change. A font anything still references is refused with a 409 `resource_in_use` listing the referencing rows — the saved presets that chose it — and references are never silently cleared. Requires `customisers:write` and an `Idempotency-Key`; retrying the same request and key replays the original receipt after the row is gone. The delete clears the customiser's cached storefront configuration and runs the advisory language sync, and never regenerates Shopify products, product images, or the product cache.
