# Update a product

PATCH https://www.your-store.co.il/api/v1/products/{id}
Content-Type: application/json

Changes only the fields sent. `categoryIds` replaces the product's categories. Requires `products:write`.

Reference: https://docs.coi.co.il/products/update-product

## Authentication

- `Authorization` header (bearer token, required) — An API key from the store's admin: חנות > API ומפתחות. Send it as `Authorization: Bearer coi_sk_...` (or `X-Api-Key: coi_sk_...`). Never in the URL - `?apikey=` is refused with 400.

## Request

- `active` (boolean, optional, default: true)
- `urlName` (string, optional) — The page address. Made from the name on create when not sent; kept unique among the store's pages.

## Response

### 200

The updated product.

- `ok` (true, optional)
- `data` (Product, optional)

## Errors

### 400 Bad Request Error

The request is not valid - a field of the wrong type, a missing field, a bad parameter.

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 401 Unauthorized Error

Missing, invalid, revoked or expired API key. The same answer for all of them.

- `ok` (false, optional)

### 403 Forbidden Error

The key lacks the permission (`insufficient_scope`), or the site's plan does not include the API (`plan_required`).

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 404 Not Found Error

No such row in this store (ids of another store are never found).

- `ok` (false, optional)
- `error` (ErrorError, optional)

### 429 Too Many Requests Error

More than 120 requests a minute with one key. Wait `Retry-After` seconds.

- `error` (ErrorError, optional)
