# List product variants

`GET /companies/{company}/products/{product}/variants`

## Request

- Base URL: `https://api.factuarea.com/v1`
- URL: `https://api.factuarea.com/v1/companies/{company}/products/{product}/variants`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

List the variants configured for a product, including optional price and stock overrides.

## Path parameters

- `company` string, uuid, required
- `product` string, uuid, required

## Query parameters

- `limit` integer
- `starting_after` string, uuid, nullable
- `active` boolean

## Headers

- `Factuarea-Version` string, date

## Response `200`

- object: Cursor-paginated list envelope shared by every v1 listing endpoint. `data` holds the page items; `has_more` signals whether another page exists; `next_cursor` is the cursor to pass back for the following page. Treat it as strictly opaque: send it through verbatim, never parse it and never assume a format — it is not the same across listings, and each listing documents its own cursor parameter. Concrete listings narrow `data` to their resource type via `allOf`.
  - `data` object[], required: Items on the current page.
    - `id` string, uuid, required
    - `object` 'product_variant', required
    - `product_id` string, uuid, required
    - `name` string, required
    - `sku` string, nullable, required
    - `barcode` string, nullable, required
    - `base_price_override` string, nullable, required
    - `unit_cost_override` string, nullable, required
    - `gross_weight_kg` string, nullable: Own gross transport weight in kg per BASE unit (decimal string, up to 4 decimals, greater than 0) that replaces the product weight for this variant; `null` inherits the product weight. Rejected with 422 `gross_weight_not_allowed` when the product base unit is a mass unit.
    - `manage_stock` boolean, required
    - `stock` string, required
    - `low_stock_threshold` string, nullable, required
    - `specifications` object, required: Technical specifications OWN to this variant (informational, not selectable). Empty object `{}` when there are none. `base_price_override` stays PER BASE UNIT, unlike a presentation price, which is per commercial unit.
    - `active` boolean, required
  - `has_more` boolean, required: Whether more pages are available after this one.
  - `next_cursor` string, nullable, required: Opaque cursor for the next page, or `null` when `has_more` is `false`. The example below shows the shape used by most listings; others return a different one, so pass the value back verbatim instead of validating it.

## Other responses

- `400`: `parameter_unknown` with `subcode` `retired_active_profile_header`: the retired `X-Active-Profile` header was sent; the company goes in the path. `parameter_invalid_format` on `Factuarea-Version`: the header is not a `YYYY-MM-DD` date. `unsupported_api_version`: the `Factuarea-Version` date is not a supported version.
- `401`: Missing or invalid API key.
- `403`: The request is authenticated but not allowed: the API key lacks the required scope (`insufficient_scope`), the plan does not include the public API or this feature (`addon_not_active`, `feature_not_available_in_plan`), or the module is not available with a test key (`module_not_available_in_sandbox`).
- `404`: The requested resource does not exist or belongs to another company.
- `422`: Validation failed. The `error.param` field identifies which input is invalid.
- `429`: Rate limit exceeded. Retry after the duration in `Retry-After`.
- `500`: Unexpected server error.
