Summary
- Implement additional improvements for payment flows, credit note handling, webhook processing, and admin UI.
Payment & Checkout
- Add Pay Now (Instant Payment) support with correct transaction state handling (paid vs configured state)
- Implement async payment flow with early order data persistence (saveEarlyOrderData) before hosted checkout redirect
- Add external_reference_id field to mondu_order_data for better order tracking
- Clean up stale mondu_order_data entries from failed payment attempts on successful finalize (deleteStaleOrderData)
- Improve shipping address resolution with billing address fallback
- Fix CLI setup issues
Credit Notes
- Add credit note cancellation endpoint (/api/mondu/orders/{orderId}/credit_notes/{creditNoteId}/cancel)
- Mark cancelled credit notes with invoice_state = 'cancelled' in both live and versioned contexts
- Unlink cancelled credit notes from parent invoice (referencedDocumentId = null) so merchants can create new credit notes
- Intercept document deletions via PreWriteValidationEvent to cancel credit notes in Mondu API before CASCADE removes DB records
- Use referencedDocumentId for parent invoice lookup with fallback to invoiceNumber
- Skip zero-amount credit notes (grossAmountCents <= 0) to prevent Mondu API 422 errors
- Filter credit line items by cutoff date to only include items belonging to the current credit note
Invoices
- Add invoice_state column to mondu_invoice_data (migration)
- Track cancelled invoice state for accurate Claim at Mondu calculation
- Improve invoice cancellation flow with Storno document support (StornoSubscriber)
- Fix invoice re-submission after cancellation
- Handle Zugferd document types (zugferd_credit_note, zugferd_embedded_credit_note, etc.)
Webhooks
- Handle order/canceled and order/cancelled webhook topics (previously fell through to "Unregistered topic")
- Use getTransactions()->last() instead of first() to correctly handle payment retries (prevents picking up old cancelled transaction)
- Guard vIBAN update with null check to prevent WriteTypeIntendException when webhook arrives before order data is created
- Implement ShopUrlService for correct webhook URL registration across sales channels
- Add backward state transition protection to prevent invalid payment state regressions
Flow Builder Events
- Add custom Mondu events: MonduOrderConfirmedEvent, MonduOrderPendingEvent, MonduOrderDeclinedEvent, MonduOrderCancelledEvent, MonduOrderApprovedEvent
- Implement MonduBusinessEventCollector for Flow Builder integration
- Dispatch events from webhook handlers and finalize flow
Admin UI
- Add "Cancel Credit Note" button to order document card
- Add "Mondu Status" display on order detail page
- Add API test button in plugin configuration
- Update translations (EN, DE, FR, NL)
- Build admin assets with Vite (stable filename without content hash)
Configuration
- Add configurable order transaction state (paid/authorized) per sales channel
- Add auto-transition order state toggle
- Add extended logging toggle
- Add skip order state validation option (migration)
Logging
- Guard all mondu.INFO log entries with isExtendedLogsEnabled() check
- Add dedicated Mondu log channel via monolog configuration
Database Migrations
- Migration1728850000MigrateSkipOrderStateValidation — add skip validation config
- Migration1729027200AddExternalReferenceId — add external_reference_id to mondu_order_data
- Migration1745900000AddInvoiceState — add invoice_state to mondu_invoice_data (with TABLE_SCHEMA = DATABASE() fix)
## [1.6.1] - 2025-12-18
### Added
- **Payment Method Specific Logos**: Each Mondu payment method now displays its own unique logo in the admin panel and storefront footer
- Invoice (Net 30): `invoice_white_rectangle.png`
- SEPA Direct Debit: `sepa_white_rectangle.png`
- Installment Payments: `installments_white_rectangle.png`
- Pay Now: `instant_pay_white_rectangle.png`
- New `PAYMENT_METHOD_LOGOS` constant in `PaymentMethods` class for logo mapping
- `getPaymentMethodLogoMediaId()` method in `MediaProvider` for handling payment-specific logos
- `hasMediaAlreadyInstalledByName()` method for checking existing media by custom name
- **Address Additional Fields Handling**: New configuration options for handling Shopware's additional address fields
- `handlingAddressAdditionalField1` - Configure how to handle Address Additional Field 1
- `handlingAddressAdditionalField2` - Configure how to handle Address Additional Field 2
- Options: Ignore, Add to Mondu Address Line 1, or Add to Mondu Address Line 2
- Applies to both billing and shipping addresses
- New configuration methods: `getHandlingAddressAdditionalField1()` and `getHandlingAddressAdditionalField2()`
- **Payment State Handling**: Fixed transaction state handling when "Authorized" is configured as the payment state
- Previously, the configured "Authorized" state was not properly applied after successful order placement
- Now correctly calls `transactionStateHandler->authorize()` when "Authorized" is selected in plugin configuration
- Ensures proper order workflow for merchants using authorization-based payment flows
### Changed
- **Refactored Resource Path Handling**: Replaced hardcoded paths with Dependency Injection
- Added `$pluginPath` parameter to `MediaProvider` constructor
- Introduced `mondu.plugin.path` parameter in `services.xml`
- Resource paths now use `%kernel.project_dir%` Symfony parameter
- Improved testability and configurability
- Updated `updatePaymentMethodImage()` to use specific logos per payment method with fallback to default logo
### Fixed
- **Critical Bug**: Fixed `TypeError` during plugin uninstallation
- Changed `MonduClient::$key` property from `string` to nullable `?string`
- Resolved "Cannot assign null to property MonduClient::$key of type string" error
- Plugin can now be safely uninstalled without errors
### Technical Improvements
- Better adherence to Shopware 6 best practices for resource management
- Eliminated use of `dirname(__DIR__)` in favor of dependency-injected paths
- Enhanced code maintainability and readability
- All paths are now configurable through Symfony DI container
## New Features
- **Differentiated Transaction States**: Declined → `Failed`, Cancelled → `Cancelled` (previously both were `Failed`)
- **Flow Builder Translations**: Added proper German/English translations for all Mondu events
---
## Breaking Changes:
- **new naming of Mondu payment methods**
Now you have to include Mondu's Privacy Information for Buyers in your terms & conditions section. Please check this site for more details: https://docs.mondu.ai/v0.7/docs/mondu-data-processing

## Bug Fixes
### Critical Fixes
1. **Sales Channel Configuration**
- Fixed: Plugin now respects per-sales-channel settings instead of global configuration
- Impact: Multi-tenant setups work correctly
2. **Checkout Decline/Cancellation**
- Fixed: Order State no longer cancelled when user declines/cancels on checkout
- Impact: Users can retry payment, better checkout experience
3. **Skip All Validations Mode**
- Fixed: "Invoice number required" error
- Impact: Works with or without invoice document
