Build with AI Agent

Use the Back4app AI Agent to generate a real luxury marketplace app from this template, including frontend, backend, auth, and transaction and authentication flows.

Back4app AI Agent
Ready to build
Create a luxury goods marketplace backend on Back4app with this exact schema and behavior.

Schema:
1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system).
2. Product: owner (Pointer to User, required), details (String, required), authentication (String, required); objectId, createdAt, updatedAt (system).
3. Transaction: user (Pointer to User, required), product (Pointer to Product, required), timestamp (Date, required); objectId, createdAt, updatedAt (system).
4. Authentication Log: user (Pointer to User, required), product (Pointer to Product, required), action (String, required); objectId, createdAt, updatedAt (system).

Security:
- Only the user can update/delete their profile. Only the owner can create/delete their transactions and products. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List users, create transactions, authenticate products, and manage access logs.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for user profiles, products, transactions, and authentication records.
