Connect nopCommerce with Mollie for Secure Payments and Reliable Payment Processing The nopStation Mollie Payment Plugin connects nopCommerce with Mollie's hosted payment experience, allowing customers to complete payments through a secure Mollie checkout while keeping the nopCommerce order flow familiar. The plugin verifies payment status directly with Mollie before marking an order as Paid, helping merchants maintain a reliable and accurate payment process.
The plugin provides a secure, store-scoped integration with Mollie and supports controlled payment-method availability based on the store, order amount, currency, billing country, customer role, and shopper context. Merchants can manage Test and Live credentials, configure available payment methods, control their display order, and use customer-role-based access from the nopCommerce administration area.
Payment operations are designed to remain reliable even when a customer does not return to the store or a notification is missed. The plugin uses authenticated Mollie status verification, handles duplicate payment notifications safely, maintains payment and refund history, and performs scheduled reconciliation for stale payments and asynchronous refunds. This allows merchants to recover payment status after missed webhooks, application downtime, or temporary service interruptions.
Feature Overview
- Secure Mollie Hosted Checkout Send customers to Mollie's hosted checkout to complete their payment. nopCommerce does not treat a browser return or webhook message as proof of payment. Instead, the plugin retrieves the current payment from Mollie and verifies its order association, amount, currency, mode, and payment method before applying the payment status.
- Dynamic Payment Method Availability Show payment methods based on the actual checkout context. The plugin can support Card, iDEAL, PayPal, Pay by Bank, and bank transfer when the method is enabled in Mollie, supported by the plugin, enabled for the current store, allowed for the customer role, and considered eligible by Mollie for the current transaction.
- Test & Live Environment Management Configure Mollie separately for Test or Live mode and keep credentials store-scoped. The administration area displays only the credential fields relevant to the selected environment, while the Test Connection action helps administrators verify the configured connection.
- Payment Lifecycle Management Handle successful, open or pending, failed, canceled, and expired payments. Eligible pending orders can also use Retry Payment, allowing customers to attempt payment again when appropriate.
- Full & Partial Refunds Manage full and partial refunds through normal nopCommerce order workflows. The plugin protects the remaining refundable amount and accounts for pending refund amounts, while asynchronous Mollie refunds remain pending until Mollie confirms their final status.
- Payment Cancellation & Void Attempt cancellation only when Mollie reports that the payment can be canceled. This prevents cancellation actions from being performed when the provider does not allow them.
- Automatic Payment Recovery & Reconciliation Recover payment and refund status when browser returns or webhooks are missed. A scheduled reconciliation process runs every five minutes for stale active payments and asynchronous refunds, helping the store recover after application downtime, missed notifications, or temporary API or credential failures.
- Reliable Payment Processing Create Mollie payments using idempotent processing and safely handle duplicate browser returns or webhook deliveries. Invalid or unknown webhook identifiers cannot change an order, while operational logs are designed to exclude credentials, payment bodies, card data, and customer personal information.
- Multi-Store Support Configure the Mollie integration separately for each nopCommerce store. Enabled status, Test/Live mode, credentials, payment-method selection, display order, cache settings, and customer-role mappings remain store-scoped, helping merchants maintain separate configurations across multiple stores.
- Payment Operation History & Diagnostics Maintain durable payment attempts, refund history, and safe order-level diagnostics so administrators can review payment operations from the nopCommerce administration area.
