Draw a diagram of the integration between the frontend, backend, and product storage system (1C/warehouse), considering personal prices for different user types. Explain what methods you will use.

To integrate the frontend, backend, and inventory system (e.g., 1C or warehouse) considering personalized prices for different user types, the following scheme can be used:

1. Frontend sends requests to the backend with the user ID.
2. Backend processes the request, authenticates the user, and determines their type (e.g., wholesale client, retail customer).
3. Backend requests current product data and base prices from the inventory system (1C/warehouse).
4. The backend calculates personalized prices considering the user type and possible discounts.
5. The backend returns a list of products with personalized prices to the frontend.

Methods that can be used:

• REST API for interaction between frontend and backend.
• Web services or API of 1C for obtaining product data and prices.
• Caching personalized prices on the backend to improve performance.
• Authentication and authorization (JWT, OAuth) to determine user type.
