Sign Customiser

Clears one of a choice's two picture slots and deletes the stored file, returning a receipt naming what was removed and the extra as it now stands. Requires customisers:write and an Idempotency-Key.

DELETE/api/v3/customisers/{customiser_id}/extras/{extra_id}/choices/{choice_value}/images/{image_slot}

Overview

Deleting from a slot that holds no image answers 404. Nothing is refused: a choice with no picture is the state every extra created over this API starts in, and the customer customiser draws such a choice as its label. 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.
