Determine what data and actions the new public frontend should receive from the existing MODX, and implement the necessary integration layer.

Do not transfer internal business logic to the frontend and do not rewrite the backend without a separate necessity.

Pay special attention to ensuring that the existing user account, passes, vehicle entry, utilities, and other internal processes continue to work without changes for users.

Define and implement a secure interaction layer between the new frontend and MODX data and functions.

Organize integration of the new frontend with the existing MODX backend

Кстати, важное уточнение: несмотря на то, что modxSite реализует АПИ, запросы используют не json данные на вход, а классический multipart/form-data
