# Validation

The `BookingForm` you submit to create an `Order` must be complete and valid. You can check the validity of the form (though some validations will only be checked at the time of order creation and you must handle the error properly)

{% tabs %}
{% tab title="iOS" %}

```swift
let errors: [BookingFormError] = bookingForm.validate()
```

{% endtab %}

{% tab title="Android" %}

```java
List<BookingFormError> errors = bookingForm.validate();
```

{% endtab %}
{% endtabs %}
