# Callbacks

zloma\_stance uses `ox_lib` server callbacks for permission checks, data loading, and active fitment recovery.

***

## Registered Callbacks

| Callback                     | Description                                                       |
| ---------------------------- | ----------------------------------------------------------------- |
| `zloma_stance:canUseZone`    | Checks whether the calling player can use a specific fitment zone |
| `zloma_stance:getWheels`     | Loads saved wheel data for a vehicle plate                        |
| `zloma_stance:getActivePool` | Returns the current server cache of active fitment entries        |

***

## `zloma_stance:canUseZone`

Used by the client before opening the menu.

```lua
local allowed, reason = lib.callback.await('zloma_stance:canUseZone', false, zoneId)
```

| Param       | Type                 | Description                                  |
| ----------- | -------------------- | -------------------------------------------- |
| `zoneId`    | string               | Zone key from `Config.FitmentZones`          |
| **Returns** | boolean, string\|nil | Allowed status and an optional denial reason |

***

## `zloma_stance:getWheels`

Loads saved wheel data for a vehicle plate.

```lua
local data = lib.callback.await('zloma_stance:getWheels', false, plate)
```

This callback does a plate lookup and returns the saved `stance` and `camber` structure if one exists.

***

## `zloma_stance:getActivePool`

Used when a player joins so already-active vehicles can receive their stance visually.

```lua
local activePool = lib.callback.await('zloma_stance:getActivePool', false)
```

Return shape:

```lua
{
    [plate] = {
        data = { ... },
        absData = { ... }
    }
}
```

`absData` contains the normalized absolute values used for direct application and sync.

***

## Internal NUI Callbacks

These are internal UI callbacks, not public integration endpoints, but they are useful for understanding the flow:

* `preview`
* `apply`
* `cancel`
* `rotate`
* `zoom`
