eSewa's official WooCommerce plugin breaks when eSewa updates its API
eSewa has an official WooCommerce plugin, but it is updated irregularly. When eSewa updates its ePay API — which it has done multiple times — stores relying on the official plugin begin experiencing payment failures that are difficult to diagnose because the error messages from the plugin are not specific. Customers reach the eSewa payment screen and are either unable to complete the transaction or are returned to the WooCommerce store with an order status that does not match what happened in eSewa's system. For production WooCommerce stores that depend on eSewa as a primary payment method, a custom plugin built directly against eSewa's ePay API is more reliable than the official plugin. It gives your development team direct control over the integration logic and means a future eSewa API update does not break checkout until an official plugin update is eventually released.
