# Get product

GET https://api.md.tiankii.com/v1/products/{id}

## Get product by ID

Returns a single product owned by the authenticated store, together with its fully expanded modifiers (including modifier options) and linked apps (id + name).

### Authentication

Requires a Merchant API key in `x-api-key` with scope `Merchant.product.read`.

### Path params

* `id` (required) — the product UUID.

### Response

Returns an object with:

* `product` — the product fields (with `productCategory`, `modifiers`, `apps` relations excluded from this sub-object).
* `modifiers` — array of full modifier objects, each including its `options`.
* `apps` — array of `{ Id, Name }` for linked apps.

Responds 400 `Product with id <id> not found` if the product does not exist in your store.

***

**Notas:** The product must belong to the caller's store; otherwise 400 (BadRequestException, not 404). modifiers include nested options; apps are projected to Id + Name only.

Reference: https://docs.tiankii.com/api-reference/tiankii-api-api-key/products/get

## Authentication

- `x-api-key` header (required)

## Request

### Path parameters

- `id` (string, required) — The product UUID.

### Headers

- `x-application-account-id` (string, optional) — Scope the request to a specific store / account instead of the one resolved from the API key. Aliases: the `x-account-id` header, or the `application_account_id` / `account_id` query parameter.
