This is the only way to stop a code: there is no delete, and the coupon stays in the catalogue with `active:false` so its past redemptions remain auditable. Once deactivated it reads as unknown to the till, so `POST /v1/coupons/validate` starts answering 404 for that code and checkout can no longer consume it. There is no reactivate — re-create the code if you archived it by mistake. 404s when no coupon carries the id. ## OpenAPI ````yaml /openapi.json post /v1/coupons/{id}/deactivate openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
