Sign Customiser

Removes the colour and returns a deletion receipt: a snapshot of exactly what was removed, so the caller can verify and report the change. A colour anything still references is refused with a 409 resource_in_use listing the referencing rows — references are never silently cleared.

DELETE/api/v3/customisers/{customiser_id}/colours/{colour_id}

Overview

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.

Required scope: customisers:write
