Summary of Changes

Hello @AdyenAutomationBot, 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 contains automatically generated code updates for the Adyen Management APIs and Balance Control API. The changes primarily involve refactoring the underlying API client logic for improved error handling and request sending, along with minor stylistic formatting adjustments and documentation updates across various service and model files.

Highlights

• API Client Refactoring: The core logic for sending API requests and handling HTTP responses has been centralized within the common.SendAPIRequest function. This eliminates redundant error handling and JSON unmarshalling code from individual API service files, leading to cleaner and more maintainable code.
• Code Formatting & Readability: Various Go files have received minor stylistic updates, including changes to import statement formatting, multiline curly braces for return statements, and single-line array declarations for enum values. These changes improve overall code consistency and readability.
• Documentation Updates: Minor textual adjustments and formatting improvements have been applied to inline comments and API documentation strings across several service files, enhancing clarity for developers.

Code Review

This pull request appears to be from an automated code generation process, introducing mostly formatting changes and updates to services and models. However, there are a few critical issues that need to be addressed. Several files have had necessary imports like encoding/json and io/ioutil removed, which will cause compilation errors. Additionally, io/ioutil is deprecated and should be replaced with io. There is also significant code duplication in error handling across many of the API methods, which should be refactored. Finally, there are some minor formatting inconsistencies that should be addressed in the code generator.
