# Adding Packages

When adding packages, there may be certain **Variables** associated with them. These can be filled by providing a `variable_data` object.

```json
"variable_data": {
    "variable_identifier": "value"
}
```

## Deliverable Types and Variable Data

### Gift Card

Packages that deliver a gift card to the user should include `giftcard_to` mapped to the e-mail address that will receive the gift card:

```json
{
    "package_id": "6276316",
    "quantity": 1,
    "variable_data": {
        "giftcard_to": "tebex-integrations@overwolf.com"
    }
}
```

### Discord Action

Packages that deliver Discord actions should include the user's `discord_id:`

```json
{
    "package_id": "6276316",
    "quantity": 1,
    "variable_data": {
        "discord_id": "000000000000000000"
    }
}
```

### Game Server Commands 

Packages that deliver game server commands should include the `username_id` of the user, dependent on your store type.

You can get the **username\_id** after creating the basket if you provide the player's username at the time of creation. See **Creating a Basket** for specific details on Game Servers.

```json
{
    "package_id": "6276316",
    "quantity": 1,
    "variable_data": {
        "username_id": "9e65a968ee4743d19a2a4c9969154491"
    }
}
```

### Custom Data

You can also provide custom data when adding packages which can be referenced by the seller as part of the transaction.

```json
{
    "package_id": "6276316",
    "quantity": 1,
    "variable_data": {
        "username_id": "9e65a968ee4743d19a2a4c9969154491"
    },
    "custom": {
        "key": "value"
    }
}
```

### Specifying the Package's Game Server

If a package with a **Game Server Command** has the configuration option:

* `Allow customers to select the game server they want to receive this package on.`

You can specify the target game server in the request by including `server_id` in your package's `variable_data`:

```json
{
    "package_id": "6276316",
    "quantity": 1,
    "variable_data": {
        "server_id": "127444"
    }
}
```

A list of your `server_ids` can be found in your [Tebex Control Panel](https://creator.tebex.io/game-servers) by clicking **Edit** beside your relevant game server. The server ID is the number at the end of the URL when editing the game server.
