# Create a product

> Create a product (SKU layer above passports). Category picks the template. Accepts imageUrls[] for CDN images (max 20). Idempotency-Key supported.

```http
POST /api/v1/products
```

Create a product. The category template is resolved automatically from the `category` slug — must match a seeded category (e.g. `batteries`, `textiles`, `jewelry`). Model strings are unique within the workspace.

Counts as one v1 write. Honours `Idempotency-Key`. Optional `imageUrls` accepts an array of public HTTPS URLs (max 20 per product, max 2048 chars each); the customer's CDN remains canonical and TracePass doesn't re-host them. Use the multipart upload endpoint when you don't have CDN URLs ready.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `Authorization` | header | string | yes | `Bearer <token>` — either a `tp_` API key (Developer → API Keys; simplest, for server-to-server) or an OAuth 2.0 access token (Developer → OAuth Apps; for user-authorized apps, scoped + revocable). The Authentication page has the full OAuth flow and scope list. |
| `Idempotency-Key` | header | string | no | UUID v4 per logical operation. |
| `name` | body | string (1-200) | yes | Display name. |
| `model` | body | string (1-100) | yes | Model identifier. Must be unique within your workspace. |
| `category` | body | string | yes | Seeded category slug — `batteries`, `textiles`, `jewelry`, `electronics`, `furniture`, `chemicals`, `packaging`, `toys`, `fmcg`, `tyres`, `iron-steel`, `construction`. |
| `description` | body | string (≤ 2000) | no | Optional description. |
| `defaultFieldValues` | body | object | no | Seed values applied to every passport created from this product. Each entry's key must exist on the category template. |
| `imageUrls` | body | string\[\] (max 20) | no | Public HTTPS image URLs. Replaces the existing array on PATCH; appends on the multipart upload endpoint. |
| `sourceLocale` | body | string (ISO 639-1) | no | Locale of `name` and `description`. Defaults to your workspace's `defaultSourceLocale` (typically `en`). |
