Summary of Changes

Hello @gcatanese, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request is a significant update to the Legal Entity Management (LEM) services and models, bringing them in line with LEM v4 of the Adyen API. The changes primarily involve updating API versions and base paths, along with substantial modifications to data models to support new functionalities and improved data capture. This includes refining existing business line definitions, expanding document types, and introducing new entities for financial and support information. The update also broadens the scope of 'Source of Funds' data, allowing for more detailed and varied financial reporting.

Highlights

  • API Version Upgrade: The core change involves updating the OpenAPI document version from v3 to v4 across all service and typing files within the legalEntityManagement directory. This includes modifying the API_BASEPATH in service files to reflect the new API version.
  • Business Line Model Refinements: The BusinessLine and BusinessLineInfo models have been refined by removing the deprecated capability field and its associated enum. Additionally, the ServiceEnum in these models now includes a new issuing option, expanding the supported business line services.
  • Document Type Expansion: The Document model now supports a new document type, proofOfDirector, enhancing the verification capabilities for organizational entities.
  • Introduction of New Models: Two new models, Financier and Support, have been introduced. Financier captures details about financial contributors (amount, name, location), while Support provides contact information (email, phone). These new models are integrated into existing structures like Individual and Organization where relevant.
  • Enhanced Data Models: Several existing models, including Individual, Organization, SoleProprietorship, SourceOfFunds, TaxInformation, Trust, and UnincorporatedPartnership, have received new fields. Notable additions include doingBusinessAsAbsent and registrationNumberAbsent for various entity types, support for Individual and Organization, and a significant expansion of SourceOfFunds with new types and detailed financial attributes.

Code Review

This pull request updates the Legal Entity Management (LEM) services and models to support LEM v4. The changes primarily consist of updating the API endpoint versions from v3 to v4 across all relevant service files and modifying the data models to align with the new API specification. This includes removing deprecated fields, adding new ones, and adjusting types. The changes appear to be consistent with a major version upgrade. My review includes a suggestion to improve maintainability by centralizing the duplicated API base path constant.
