Delete an extra image

Clears one of the extra's image 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`. Deleting from a slot that holds no image answers 404. 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.

Authorisation

The Authorization header expects a Bearer token. Generate one on the API keys page in your dashboard.
