GoKwik Integration to Disable COD at Checkout

REQUEST_SUMMARY_V2 Problem - Current System: When a customer opts for Cash On Delivery (COD), a draft order is created. The customer is then taken to a Shopify checkout where they still have the option to choose COD, leading to automatic cancellation of orders based on payment type. Suggested Feature: Implement an integration with GoKwik to provide a specialized checkout experience. Upon choosing COD, customers should receive a link directing them to a GoKwik checkout where the COD option is disabled. This aims to encourage customers to complete their purchase using prepaid methods without the need for creating a new draft order.
