Multi-Service Super App Backend

Multi-Service Super App Backend Template
Transport Services and Integration

Q: What is a multi-service super app backend?

A multi-service super app backend is a BaaS schema and API designed for unified service management and transaction visibility: users, services, and transactions.

Q: What does the Multi-Service Super App template include?

It includes User (username, email, password), Service (type, provider, specifications), and Transaction (user, service, status), ER diagram, API playground, and an AI Agent prompt.

Q: Why use Back4app for a multi-service app?

Back4app provides a managed database, authentication, real-time queries, and a flexible schema so you can ship unified service management and transaction visibility without running your own backend.

Q: How do I run queries for services and transactions with Flutter?

Use the Service and Transaction classes to query and display services and transaction statuses, leveraging the Back4app SDK.

Q: How do I manage access with Next.js server actions?

Use a server action to create a Parse Object for Transaction with user pointers and permissions. Optionally validate in Cloud Code.

Q: Can React Native cache services and transactions offline?

Yes. Enable Local Datastore and pin Service and Transaction results so users can access saved services and transactions without connectivity.

Q: How do I prevent unauthorized service access?

In Cloud Code beforeSave for Service, ensure appropriate permission checks and reject if unauthorized access is detected.

Q: What is the best way to show services and transactions on Android?

Query Service and Transaction classes to display available services and user transaction statuses, utilizing the Back4app SDK for data management.

Q: How does the service interaction flow work end-to-end?

Users can select services and create transactions which update in real-time through Live Queries for immediate notifications.

Build with AI Agent

Use the Back4app AI Agent to generate a real multi-service app from this template, including frontend, backend, auth, and service transaction flows.

Back4app AI Agent

Ready to build

Create a multi-service super app backend on Back4app with this exact schema and behavior.

Schema:
1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system).
2. Service: type (String, required), provider (String, required), specifications (JSON, required); objectId, createdAt, updatedAt (system).
3. Transaction: user (Pointer to User, required), service (Pointer to Service, required), status (String, required); objectId, createdAt, updatedAt (system).

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

Auth:
- Sign-up, login, logout.

Behavior:
- List users, select services, create transactions, and manage access.

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