{% code overflow="wrap" %}

```php
apply_filters( 'elementor_pay_addons/forms/record/actions_before', $record, $this )

apply_filters('elementor_pay_addons/api/checkout_session_args', $session);

apply_filters( 'elementor_pay_addons/webhook/event', $event);

apply_filters( 'elementor_pay_addons/form/create_customer', $customer_params );

apply_filters( 'elementor_pay_addons/form/create_payment_intent', $payment_intent );

apply_filters('elementor_pay_addons/form/create_subscription', $subscription_params);

apply_filters( 'elementor_pay_addons/form/create_checkout_session', $checkout_session );

apply_filters('elementor_pay_addons/email/format_string', str_replace($find, $replace, $string), $this);

apply_filters('elementor_pay_addons/email/headers', $header, $this->id, $this->object, $this);

apply_filters('elementor_pay_addons/email/from_name', get_option('epa_email_sender_from_name'), $this, $from_name);
```

{% endcode %}

### Access Stripe Instance in front-end JS

{% hint style="danger" %}
Make sure to fetch the form handlers after DOM is ready.
{% endhint %}

Let's say you want to get Stripe [payment element](https://docs.stripe.com/js/element/payment_element) in [Checkout Element Form](/elements/checkout-element-form-pro.md): 

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.getElement('payment')
```

{% endcode %}

Let's say you want to get Stripe [card element](https://docs.stripe.com/js/elements_object/create_element?type=card) in [Checkout Credit Card Form](/elements/checkout-credit-card-form-pro.md): 

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.getElement('card')
```

{% endcode %}

Then we can execute the Stripe native method such as update in the front end.

{% code overflow="wrap" %}

```javascript
jQuery('.elementor-widget-form')[0].epaFormHandler.stripeElement.update({ amount: total });
```

{% endcode %}
