Best Practices

You can use Curlec 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

2. Integrate Orders API

Integrate with Orders API

on your server-side and pass the order_id to Checkout.

3. Verify Signature to Avoid Data Tampering

how to 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:

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

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.
