# Create a product

`POST /v1/products`

Create a new product in your catalog. Products can be referenced when creating payments to pre-fill amount and description.

## Headers

- `X-Idempotency-Key` string, required

## Request body

- CreateProductRequest
  - `externalId` string — Your own product ID.
  - `name` string, required — Product name.
  - `description` string — Product description.
  - `amount` number — Default price.
  - `metadata` object

## Response `201`

Product created.

- object
  - `product` Product
    - `id` string, uuid
    - `name` string
    - `description` string
    - `amount` number
    - `externalId` string
    - `isActive` boolean
    - `createdAt` string, date-time

## Other responses

- `400` — Validation error.
- `401` — Missing or invalid authentication token.
- `409` — Idempotency conflict, raised by the idempotency middleware. `IDEMPOTENCY_PAYLOAD_MISMATCH` means the key was already used with a different request body, at any point in the 24-hour window, including by a request still in flight. `IDEMPOTENCY_CONFLICT` means a request with the same key and the same body is still being processed. Both use the **flat** envelope: `error` is the HTTP reason phrase and the machine-readable code is the top-level `code`. Note that `IDEMPOTENCY_CONFLICT` raised later by the withdrawal service on an idempotency-key collision uses the nested `Error` envelope instead.
