# Events

RoundlyConsulting\\Credits\\Events\\CreditsModified is dispatched after every recorded change. It carries the creditable, the new Credit row and the resulting balance:

```php
use Illuminate\Support\Facades\Event;
use RoundlyConsulting\Credits\Events\CreditsModified;

Event::listen(function (CreditsModified $event): void {
    // $event->creditable, $event->credit, $event->balance
});
```

## Payload

```php
final class CreditsModified implements ShouldDispatchAfterCommit
{
    use Dispatchable;

    public function __construct(
        public readonly Model&Creditable $creditable,
        public readonly Credit $credit,
        public readonly int $balance,   // the bucket's balance this change produced
    ) {}
}
```

balance is the balance of the bucket that changed — read it from $event->credit->bucket — not a total across buckets. It is the balance this change produced, read under the owner lock inside the change’s transaction, so a racing change never leaks into it.

## When it fires

- After every successful write — add(), deduct(), modify(), setTo() and their Money forms on a scope, the matching trait methods — and for each entity credits:modify changes.
- Only once the change is committed: CreditsModified implements ShouldDispatchAfterCommit, so inside setTo() or your own DB::transaction() listeners receive it when the outermost transaction commits — and never for a change that is rolled back. A listener that throws cannot roll the change back; check before making the change instead.
- Not when setCreditsTo() is a no-op because the balance already matches.
- Not when the overdraft guard, the 64-bit bound or a money check refuses the change — nothing was written.

## A listener

Send a receipt, update a dashboard or alert on a low balance:

```php
use Illuminate\Support\Facades\Log;

Event::listen(function (CreditsModified $event): void {
    Log::info("Balance for {$event->creditable->getKey()} is now {$event->balance}");

    if ($event->credit->amount < 0 && $event->balance < 10) {
        // $event->credit->bucket is running low — notify the owner
    }
});
```
