# GET Get a customiser

Retrieve one customiser by its integer `id` (as returned by the list operation). The response reports the customiser's pricing model (`simple_letter`, `advanced_letter` or `frame_fit`, with a human display name), its `sign_category` and `product_family`, its styling `selection_mode`, and whether it is `active` on the storefront. The operation is read-only, has no side effects, and is always safe to retry. Requires the `customisers:read` scope. A 404 problem with code `resource_not_found` means the customiser does not exist on the store your API key belongs to — use the list operation to discover valid ids; ids from another store are indistinguishable from unknown ids. A 401 problem means the key is missing, invalid, or expired. A 403 problem with code `insufficient_scope` means the key is valid but lacks `customisers:read`. A 429 problem means too many requests: wait `retry_after` seconds, then retry. Error responses use RFC 9457 problem+json with a machine-readable `code`, a documentation link in `type`, and a `request_id` to quote when contacting support.
