# POST Create a preset

Adds a preset to the customiser and returns it with the `code` the server generated for it. Both `name` and `design` are required: a preset with nothing to restore is not a starting point. `design` is the snapshot the customer customiser produces when a design is saved, and v3 stores it verbatim. Nothing in this API composes one, so an integration builds a design in the customiser (or reads it back from an existing preset) rather than authoring the document by hand. It must be a non-empty JSON object; a document above the size cap is refused, and one above the 2 MiB request-body limit is a 413 before it reaches validation. Requires `customisers:write` and an `Idempotency-Key`. The write clears the customiser's cached storefront configuration and runs the advisory language sync. It never regenerates Shopify products, product images, or the product cache, so live listings are untouched. Option writes also spend one unit of a separate per-key option-write budget; exhausting it returns a 429 with `retry_after`.
