Congratulations! You've completed the Designing APIs chapter and learned how to design professional APIs from scratch using Apidog.Throughout this chapter, you designed a complete User module for the Pet Store API, applying RESTful principles, best practices, and industry standards.
What You Built#
User Module API#
POST /users β Create user
GET /users/{id} β Get user
PUT /users/{id} β Update user
DELETE /users/{id} β Delete user
POST /user/login β Login (returns JWT)
POST /user/logout β Logout
LoginRequest, LoginResponse
Response components (400, 404, 422)
What You Learned#
1. API Design Process#
Analyze Requirements β Identify resources and operations
Design Data Models β Create schemas with validation
Design Endpoints β Configure requests and responses
Add Components β Reuse common elements
Set Up Security β Apply authentication
Follow Guidelines β Maintain consistency
2. Key Principles#
Design-First β Design before implementation
RESTful Patterns β Resource-oriented URLs with HTTP methods
Reusability β Use components and schemas
Consistency β Follow naming conventions and standards
Security β Protect sensitive endpoints
3. Apidog Features#
Generate schemas from JSON
AI naming and compliance check
Best Practices Applied#
1.
Use schemas for all request/response bodies
2.
Provide examples for requests and responses
3.
Follow RESTful URL patterns (plural nouns, hierarchical)
4.
Use appropriate HTTP status codes
5.
Standardize error responses
6.
Apply authentication to protected endpoints
7.
Use camelCase for field names
8.
Create reusable components
Next Steps#
Continue Learning#
1.
API Testing β Automate testing with test scenarios
2.
Mock APIs β Enable frontend development before backend is ready
3.
API Documentation β Publish interactive documentation
Practice More#
1.
Design additional modules (Order, Pet, Store)
2.
Try different authentication methods (OAuth 2.0, API Key)
3.
Apply these skills to real projects
Key Takeaways#
Analyze requirements and plan API structure
Design data models as reusable schemas
Create RESTful endpoints with proper configuration
Use components for consistency
Implement JWT authentication
Follow design guidelines and best practices
