<AccordionGroup>
  <Accordion title="Why are my customer payments being automatically refunded?">
    Payments made without an `order_id` cannot be captured and are automatically refunded. Create an order using the [Orders API](/docs/payments/payment-gateway/web-integration/standard/integration-steps#11-create-an-order-in-server) before initiating payments.
  </Accordion>

  <Accordion title="What can cause an overflow issue on an HTML page, and how can I resolve it?">
    Overflow issue can occur if the viewport meta tag is not present in your code. Check if the meta tag is added. If not, add the following line.

    ```html View Port Meta Tag theme={null}
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    ```
  </Accordion>

  <Accordion title="Is a timeout applicable on transactions?">
    Transaction timeout is applicable only when your customer attempts the payment. It times outs between 3 to 15 minutes.

    The customer is redirected to the checkout if a payment fails due to timeout.
  </Accordion>

  <Accordion title="Can I track the status of the checkout modal?">
    Yes, you can track the status of the checkout modal. You can do this by passing a modal object with `ondismiss: function(){}` as `options`. The `ondismiss` function is called when the modal is closed by the user.

    ```javascript Javascript theme={null}
    var options = {
        "key": "<YOUR_KEY_ID>", // Enter the Key ID generated from the Dashboard
        "amount": "29935",
        "name": "Acme Corp",
        "description": "A Wild Sheep Chase is the third novel by Japanese author Haruki Murakami",
        "image": "http://example.com/your_logo.jpg",
        "handler": function (response){
            alert(response.razorpay_payment_id);
        },
        /**
          * You can track the modal lifecycle by * adding the below code in your options
          */
        "modal": {
            "ondismiss": function(){
                console.log('Checkout form closed');
            }
        }
    };
    var rzp1 = new Razorpay(options);
    ```

    You can utilise the `handler` function called on every successful transaction for tracking payment completion.

  <Accordion title="What is the difference between webhooks and callback URL?">

    | About       | Webhooks allow you to build or set up integrations that subscribe to certain events on Razorpay APIs. When one of those events is triggered, we send an HTTP POST payload in JSON to the webhook's configured URL. <br /> Know more about [webhooks](/docs/webhooks). | A callback URL is an address that a server provides, and any computer in the Internet/private network can POST data to it. For Razorpay integrations, callback URL is the address at which Razorpay should send the transaction response. You can pass the URL in the `https://<domain_name_callback_url>` format in the `callback_url` request parameter. Know more about [callback URL](/docs/payments/payment-gateway/callback-url).                                                                                                                                                                 |
    | When to use | Use webhooks to receive real-time notifications when specific events occur. For example, receive notifications upon payment failure.                                                                                                                                  | Use callback URL to redirect your customers to a particular page. For example: <br /> <ul><li>You can send customers to a payment success page after successful payment. This page will receive payment details such as the payment id.</li><li>The Razorpay Checkout pop-up page does not appear in certain browsers, for example, on Facebook and Instagram browsers. In such cases, you can use the callback URL to redirect customers from your Facebook/Instagram page to another page where the Razorpay Checkout appears. Customers can complete the payments on this redirected page.</li></ul> |
