You can use Razorpay Custom Checkout to customise the checkout experience as per your requirements and use it as a white-label solution.

Given below are some of the best practices to be followed for smoother integration and payment experience.

## 1. Integrate Payments Rainy Day Kit

Use Payments Rainy Day kit to overcome payments exceptions such as:

* [Late Authorisation](/docs/us/payments/payments/late-authorisation)
* [Payment Errors](/docs/us/errors)

## 2. Integrate Orders API

Orders help in binding multiple payment attempts against a single order. This helps to prevent multiple payments. [Integrate with Orders API](/docs/us/payments/orders) on your server-side and pass the `order_id` to Checkout.

## 3. Verify Signature to Avoid Data Tampering

Verifying the Signature is a mandatory step that lets you confirm the authenticity of the details returned to the Checkout form for successful payments. Know more about [how to verify payment signature](/docs/us/payments/payment-gateway/web-integration/custom/build-integration#1-5-verify-payment-signature).

## 4. Check Payment or Order Status before Providing Services

Check the payment/order status, that is, if the payment's status is `captured` and the order's status is `paid` before proving the services to the customers.

You can determine payment and order status using:

* [Fetch All Payments for an Order API](/docs/us/api/orders/fetch-payments)
* [Fetch Status of a Payment using Payment id API](/docs/us/api/payments/fetch-with-id)
* [Fetch Status of an Order using Order id API](/docs/us/api/orders/fetch-with-id)

## 5. Implement Webhooks

Implement webhooks or the query API to avoid any cases of callback failure (drop-offs could be connectivity or network failure) and to verify the payment details via an S2S call. Some of the webhook events you should enable are:

* `payment.captured`
* `payment.failed`
* `order.paid`

Know more about [Webhooks](/docs/us/webhooks).

## 6. Implement Callback URL

Implement `callback_url` if your customers make online payments on browsers such as Instagram, Facebook Messenger, Opera, UC browsers and so on. This is because these browsers do not support i-frame.
