Remove a product from a review group
Authorizations
A secret API key. Publishable keys cannot reach this API. A key may carry an expiry, and an expired key is refused exactly like an unknown one, with a 401 that names no reason; check the key's expires_at in the dashboard rather than inferring it from a response. When a merchant rolls a key's secret they choose a grace window of up to 3 days, and for its duration BOTH the new secret and the one it replaced authenticate, so an integration moves over on its own deploy schedule instead of at the instant the button is pressed. Move before the window closes: after it, the old secret is refused. Nothing else about this contract moves with a roll. The key keeps its id and its scopes, so the only thing an integration updates is the credential itself.
Headers
A unique key per logical write. Replaying a request with the same key returns the first response byte for byte instead of applying the write twice.
Body
Takes no parameters, and an empty body is expected. The product reverts to its own reviews and rating. Fully reversed by POST .../members with the same product id, which is what separates this from deleting the GROUP itself: that stays refused, because dissolving a group re-points every remaining member's rating at once with nothing announcing it, where removing one product at a time is an ordinary, reviewable edit.
Response
Success. The response has no body.
