Code Review

This pull request introduces new models and webhook handling for Mandate notifications. The changes include adding MandateNotificationRequest, Mandate, MandateBankAccount, MandateBankAccountAccountIdentification, MandateNotificationData, MandatePartyIdentification, and UKLocalMandateAccountIdentification classes. Additionally, the ConfigurationWebhooksHandler has been updated to include a method for processing MandateNotificationRequest.

My review identified several areas for improvement related to error handling consistency and code efficiency, particularly in how enum values are validated and how null values are managed during deserialization. Addressing these points will enhance the robustness and maintainability of the new code.

Added test for parsing MandateNotificationRequest webhook (balancePlatform.mandate.created).

Changes:

• Created mock JSON file: src/test/resources/mocks/balancePlatform-webhooks/configuration-mandate-created.json
• Added test method testMandateCreatedNotificationRequest() in BalancePlatformWebhooksTest.java
• Test validates mandate details including balance account ID, payment instrument ID, status, type, and UK Local account identification (account number, sort code)

All tests passing ✅
