# Add a resource requirement to a service

`POST /v1/services/{serviceId}/resource-requirements`

Attaches a requirement: exactly one of `category` ("quantity N from this pool") or `resource_id` ("this specific resource") — both or neither is 422 `REQUIREMENT_TARGET_INVALID`, and a specific resource takes quantity 1 (422 `REQUIREMENT_QUANTITY_INVALID`). A `resource_id` from another workspace collapses onto 404 `RESOURCE_NOT_FOUND`; a duplicate target for the same service is 409 `REQUIREMENT_ALREADY_EXISTS`. Owner/admin only. Per-user rate-limited at 60/60s.

## Path parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `serviceId` | `string` | Yes |  |

## Headers

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `X-Wiblo-Workspace` | `string` | Yes | Workspace id the call is scoped to. The actor must hold an active membership in it; a foreign or unknown id collapses onto 404 WORKSPACE_NOT_FOUND. |

## Request body

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `category` | `string \| null` | No | Resource category to draw from; exactly one of `category` and `resource_id` must be set. |
| `resource_id` | `string \| null` | No | A specific resource the service needs; exactly one of `category` and `resource_id` must be set. |
| `quantity` | `integer` | No | How many distinct free resources the category's pool must supply per booking; must be `1` for a specific-resource requirement. Defaults to `1`. |

## Responses

**`201`** — Requirement created. Returns `ResourceRequirementResponse`.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | `string` | Yes | Unique id of the requirement. |
| `workspace_id` | `string` | Yes | Workspace the requirement belongs to. |
| `service_id` | `string` | Yes | Service the requirement is attached to. |
| `resource_id` | `string \| null` | Yes | The specific resource required; `null` for a category requirement. |
| `category` | `string \| null` | Yes | The category pool drawn from; `null` for a specific-resource requirement. |
| `quantity` | `integer` | Yes | How many distinct free resources the category's pool must supply per booking; always `1` for a specific-resource requirement. |
| `created_at` | `string` | Yes | Creation timestamp (RFC 3339). |
| `updated_at` | `string` | Yes | Last-update timestamp (RFC 3339). |

**`400`** — Body failed Zod validation (`VALIDATION_FAILED`). Returns `ApiErrorEnvelope`.

**`401`** — No valid session cookie or `wbl_*` bearer was present. Returns `ApiErrorEnvelope`.

**`403`** — The actor is a plain member; owner or admin is required (`ADMIN_REQUIRED`). Returns `ApiErrorEnvelope`.

**`404`** — The service or the named resource collapsed (`SERVICE_NOT_FOUND` / `RESOURCE_NOT_FOUND` / `WORKSPACE_NOT_FOUND`). Returns `ApiErrorEnvelope`.

**`409`** — The service already requires this category or resource (`REQUIREMENT_ALREADY_EXISTS`). Returns `ApiErrorEnvelope`.

**`422`** — Not exactly one of `category` / `resource_id` (`REQUIREMENT_TARGET_INVALID`), quantity above 1 on a specific resource (`REQUIREMENT_QUANTITY_INVALID`), or a path param failed UUID validation (`INVALID_PARAMS`). Returns `ApiErrorEnvelope`.

**`429`** — Rate limit exceeded. The body's `error.code` is `RATE_LIMITED` and `error.details.retry_after` is the same number of seconds as the `Retry-After` header. Returns `ApiErrorEnvelope`.
