`POST https://api.border.bot/v1/catalog/products/{id}/classifications`

Requires an API key (`Authorization: Bearer bb_live_…`).

A code you hold for a market: a suggestion to review, or approved at once with `approve`. Markets in a customs union share its code (Germany and France the EU’s). Free.

API key scope: `catalog`.

## Parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string (uuid) | yes | The product’s id. |

## Request body (JSON)

- `401`: Missing, invalid, revoked or expired API key (`unauthorized`). (`Error`)
