A1 Yandex KIT — Store

Communication

Before producing any user-facing message, read and apply ../a1-yandex-kit/references/merchant-communication.md completely.

Covers the store-level domain of the Yandex KIT e-commerce API — tags: Магазин, Склады, Пользователи, Гео, Файлы, Редиректы, Новости, Алерты. This is where you read the store profile and the API user, manage warehouses (variant stocks reference them; UpdateWarehouse uses JSON Merge Patch), upload files (POST /v1/files — with POST /v1/videos in the catalog domain, one of the API's two multipart/form-data endpoints), and maintain SEO redirects and blog/news posts.
