# List categories
URL: https://docs.fluenta.io/en/docs/reference/organization/list-categories
Operation: `listCategories`
Required permission: `read`

`GET /v1/external/organizations/{organizationId}/categories`

The «Categorías» an OC takes its garment from: the plant’s own, for «Otros clientes», and those of each brand it works for in the «Red de talleres».

Answers the «Categorías de prenda» of «Configuración»: the kinds of garment (blusa, pantalón…) a «referencia» (an OC) is, which production figures are added up by.

`own` is the plant’s own list, plain names, for the OCs of its own clients («Otros clientes»). `brands` holds one group per brand («cuenta de marca») the plant works for in the «Red de talleres»: its `companyAdminId`, its name and its numbered catalogue (`code` «01», `short` «Blusa», `name` «Blusa · Vestido»). Both are empty for a plant that keeps no list and works for no brand.

Feed it to the «Programa»: the `garment` of `createReference` and `updateReference` takes one name of `own`, and a «referencia» read back (`getProgram`, `getReference`) carries the same string.

No id beyond `organizationId`; no time field; the read creates nothing.

Not paged: the whole answer comes in one response.

Plan: on every plan, Light included. A «token de API» reads it in any organization the user who created it belongs to; a connected AI app (a «conexión») reads it only where the organization has «Conectar con IA» (`getPlan.features.aiConnector`, a Pro feature), and answers 403 `PLAN_LIMIT` elsewhere.

Rate limit: one request of the credential’s ordinary budget in this organization (`getPlan` answers the numbers); past it, 429 `RATE_LIMITED` with `Retry-After` in seconds.

### Authorization

- `apiToken` — Bearer token. An API token created in Configuración › Tokens de API, or a connected app’s access token

Send it as `Authorization: Bearer <your API token>`.

### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `organizationId` | path | integer | yes | The organization, from `getMe` or `listOrganizations`. |

### Responses

| Status | Description |
| --- | --- |
| `200` | `ExternalCategoriesDto` |
| `401` | `INVALID_API_TOKEN`: the credential is missing, malformed, unknown, expired or revoked. One body for all of them. |
| `402` | The organization is blocked: `ORG_BLOCKED`. |
| `403` | `PLAN_LIMIT` with `feature: "aiConnector"`: the credential is a «conexión» and the organization’s plan has no «Conectar con IA» (Light). A «token de API» is not refused here on any plan on sale: the plant reads are on every plan. `INSUFFICIENT_SCOPE` only for a credential without the «Permiso» `read` («Leer»), which every credential is issued with. |
| `404` | `ORGANIZATION_NOT_FOUND`: the organization does not exist or is out of the credential’s reach. One body for both. |
| `429` | The credential is over its rate limit: `RATE_LIMITED`. Per credential, in fixed windows of 60 seconds: 60 requests in one organization on Light and 120 on Pro; 20 on the heavy reads (the range figures, the whole floor, the month and the pauses); 300 across every organization; 60 on the routes that name no organization. Wait `Retry-After` seconds; a refused request counts against nothing. |

### Example

```bash
curl -X GET 'https://api.fluenta.io/v1/external/organizations/{organizationId}/categories' \
