Frequently Asked Questions
Everything you need to know about our SaaS starter kit
Is this a REST or GraphQL API?
The starter includes a RESTful API following best practices. However, the NestJS framework supports GraphQL, so you can add GraphQL endpoints alongside REST or migrate entirely to GraphQL if preferred.
How is the API documented?
Automatic API documentation using OpenAPI/Swagger. Every endpoint is documented with request/response examples. The interactive documentation lets developers test endpoints directly. Supports API versioning documentation.
Can I build a mobile app with this API?
Absolutely! The API is designed to serve mobile apps with JWT authentication, proper CORS handling, and mobile-optimized responses. Many customers use this API with React Native, Flutter, or native iOS/Android apps.
How does API versioning work?
Built-in API versioning support using URL path versioning (/api/v1/, /api/v2/). You can maintain multiple API versions simultaneously, deprecate old versions gradually, and migrate clients smoothly.
Is rate limiting included?
Yes! Configurable rate limiting per endpoint, per user, or per IP address. Protects against abuse while allowing legitimate traffic. Includes bypass options for trusted clients and detailed rate limit headers.
Can I create a public API for developers?
Yes! Everything needed for a public API is included: API key management, OAuth2 client credentials flow, usage tracking, and developer portal foundations. Perfect for building API-first products.
How do I handle file uploads through the API?
File upload handling is built-in with support for direct uploads, multipart forms, and signed URL uploads to cloud storage. Includes file validation, virus scanning hooks, and progress tracking.
What about webhook support?
Outgoing webhooks are fully supported with retry logic, signature verification, and event queuing. Let your users subscribe to events in your system. Includes webhook testing tools and delivery tracking.
