# Assign a specific licence key to an order

`PUT https://app.filemonk.io/api/v2/external/orders/{id}/licences/{licence_id}`

Swap the licence key on the order, as the order page's Reassign does: the current key goes back to the pool and key (an unassigned key of this shop) takes its place. Without key the row is left open for the automatic assigner.

## Path parameters

- `id` (string, required)
- `licence_id` (string, required)

## Request body

- `key` (string): e.g. `ABCD-EFGH-IJKL-0002`

## Returns

The [order object](https://docs.filemonk.io/v2/api-reference/orders/).

Rate limit: this call costs 2 points ([rate limits](https://docs.filemonk.io/v2/errors-and-rate-limits/)).

## Example request

```sh
curl -X PUT "https://app.filemonk.io/api/v2/external/orders/3e84eb8d-e1d9-4e92-a4b2-a419c7f1122f/licences/{licence_id}" \
  -H "X-Auth-Token: $FILEMONK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "key": "ABCD-EFGH-IJKL-0002"
  }'
```

## 200

Success: the write completed; the body is the updated resource.

## 401

Missing or invalid API key.

```json
{
  "errors": [
    "Invalid API key"
  ]
}
```

## 404

The resource does not exist for this shop, or the action path is not registered.

```json
{
  "errors": [
    "Order not found: c3d4e5f6-7a8b-4c9d-8e0f-1a2b3c4d5e6f"
  ]
}
```

## 422

The request failed validation, or sent a key the action does not take (`code: "unknown_parameters"` with `unknown` and `accepted`). Nothing was saved.

```json
{
  "errors": [
    "access.download_limit_count must be an integer of at least 0"
  ],
  "field_errors": {
    "access.download_limit_count": [
      "must be an integer of at least 0"
    ]
  }
}
```

## 429

Rate limited. Cost-weighted per API key, shared with API v1: a read costs 1 point, a write 2, 40 points per fixed 60-second window. Every response carries `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset` (Unix time the window ends); a 429 adds `Retry-After` (seconds), `retry_after`, `retryable: true` and a `next_step` in the body. A 429 did nothing: wait `retry_after` seconds, then send the same request again. The budget is per key, so every tool or script using the key shares it; prefer one list call with `per_page` over many single reads.

```json
{
  "errors": [
    "You have exceeded the rate limit of 40 points per 60 seconds. Read requests cost 1 point(s) and write requests cost 2 point(s). Please retry after 12 second(s)."
  ],
  "code": "rate_limited",
  "retry_after": 12,
  "error": "Rate limit exceeded",
  "message": "You have exceeded the rate limit of 40 points per 60 seconds. Read requests cost 1 point(s) and write requests cost 2 point(s). Please retry after 12 second(s)."
}
```
