# A1 Yandex KIT — Promotions

## Communication

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

Covers the promotions domain of the Yandex KIT e-commerce API — tags: Скидки,
Промокоды, Группы промокодов, Подарки. Promotions are created first and then bound to
objects: discounts, promocodes and promocode groups to variants, categories or
collections via their `.../objects/add` and `.../objects/remove` endpoints (a
promocode-group request carries either variants or categories+collections, not both),
gifts to variants via `POST`/`DELETE /v1/gifts/{id}/variants`. Промокоды and
Группы промокодов are separate models: a promocode is one standalone code, while a
group holds the discount rules plus its codes — type `SINGLE` (one shared code) or
`MULTIPLE` (single-use coupon codes managed via
`/v1/promocode_groups/{group_id}/codes`). End-of-life differs per kind — **only
discounts can be archived** (`ArchiveDiscount`/`UnarchiveDiscount`, status
`ACTIVE`/`INACTIVE`/`ARCHIVED`; archived discounts stop applying but stay
restorable). Promocodes and gifts have no archive endpoints and only two statuses,
`ACTIVE`/`INACTIVE` — pause them by PATCHing `status` to `INACTIVE` via
`UpdatePromocode`/`UpdateGift`. Promocode groups also report `ACTIVE`/`INACTIVE`,
but `UpdatePromocodeGroup` is a full PUT replace with **no `status` field** — every
field is required, so resend the current values when changing anything. `DeleteGift`
removes a gift **permanently**, with no restore — prefer deactivation;
`DeletePromocodeGroup` likewise permanently deletes the group **with all its codes**.

For authentication (`Authorization: Bearer <token>`), the base URL (`https://api.kit.yandex.net`, all paths under `/v1/`), the 3 rps rate limit and the `{code, message, trace_id}` error contract, see the `a1-yandex-kit` skill.

## Workflow

Run the bundled scripts from this skill's directory — they are self-contained
(Node.js >= 20, builtins + a vendored validator, no `npm install`, no network).

1. **Search** for the operation you need:

   ```bash
   node scripts/search_docs.mjs "<query>" [--tag "<Тег>"] [--limit N]
   ```

   Matches operation ids, paths, tags and the Russian summaries/descriptions,
   e.g. `node scripts/search_docs.mjs "создать скидку"`.

2. **Inspect** the full contract of one operation — path/query parameters plus the fully
   dereferenced request/response schemas:

   ```bash
   node scripts/search_docs.mjs --operation CreateDiscount
   ```

3. **Validate** a drafted request body offline before sending anything:

   ```bash
   node scripts/validate.mjs --operation CreateDiscount --body '<json>'
   # or: node scripts/validate.mjs --operation CreateDiscount --body-file body.json
   ```

   Prints `VALID` (exit 0) or the list of schema violations (exit 1).

4. **Execute** the operation:

   - prefer the matching `mcp-yandex-kit` MCP tool from «Related MCP tools» below (e.g. `create_discount`, `manage_promocode_objects`);
   - any operation without a dedicated tool: the `kit_request` MCP tool — it validates
     the body against the same schema before sending;
   - or plain HTTP:
     `curl -H "Authorization: Bearer $YANDEX_KIT_TOKEN" https://api.kit.yandex.net/v1/...`
     (mind the 3 rps limit).

160 operations):

- `list_discounts` — List discounts of the store filtered by status (paginated).
- `get_discount` — Get a single discount by its ID (title, value, dates, status, binding mode).
- `create_discount` — Create a new discount.
- `update_discount` — Update an existing discount (plain application/json PATCH): send only the fields to change (title, discount_value, discount_dates, status, binding_mode).
- `discount_action` — Archive a discount (soft delete: status becomes ARCHIVED, the discount stops applying but stays restorable) or unarchive it (returns it to a non-archived status).
- `manage_discount_objects` — Attach objects to a discount or detach them.
- `list_promocodes` — List promocodes of the store filtered by status (paginated).

Подарки (gifts) and Группы промокодов have no dedicated tools — manage them through `search_operations` + `kit_request`.
