# (Deprecated) Load unit configuration

{% hint style="danger" %}
Load unit types API is deprecated, use instead [Operative container types](https://docs.fulfillmenttools.com/documentation/by-pillar/store-operations/packing/broken-reference).
{% endhint %}

It is possible to use **load units** within the picking process. Load units can be any kind of custom items which complement the picked task, such as **bags, boxes, vouchers, or any kind of goodies / information** that the picker should get once the picking process is finished.

## Creating a load unit type

While a `load unit` captures the information for a particular `pick job`, the `load unit type` is the configuration object.

To create a `load unit type`, send a `POST` request to the following endpoint with the JSON body.

```
POST https://{YOUR-TENANT-NAME}.api.fulfillmenttools.com/api/loadunittypes
```

```json
{
    "nameLocalized": {
        "de_DE": "Papiertasche",
        "en_US": "Paperbag",
        "pl_PL": "Torba papierowa"
    },
    "priority": 1
}
```

## Update a load unit type

To update an existing `load unit type`, send a `PATCH` request to the following endpoint with the JSON body.

```
PATCH https://{YOUR-TENANT-NAME}.api.fulfillmenttools.com/api/loadunittypes/<loadUnitTypeId>
```

```json
{
    "version": 3,
    "actions": [
        {
            "action": "ModifyLoadUnitType",
            "priority": 2
        }
    ]
}
```

All defined `load unit types` are immediately displayed for selection in the picking process. If no `load unit types` are defined, this step is skipped in the application.

{% hint style="warning" %}
A `load unit type`, once defined, cannot be deleted via the API. Contact support for assistance in this scenario.
{% endhint %}

## Add an icon to a load unit type

An icon can be added to a `load unit type` definition for display in the Operations App. This helps the picker identify which item (e.g., bag or box) to choose. The image file must be base64-encoded in the HTTP request.

To add an icon to an existing `load unit type`, send a `PUT` request to the following endpoint with the JSON body.

```
PUT https://{YOUR-TENANT-NAME}.api.fulfillmenttools.com/api/loadunittypes/<loadUnitTypeId>/icon
```

```json
{
    "name": "paperbag.png",
    "content": "==base64-encoded content=="
}
```
