Rules Design API

✍️ 1. Meaningful Endpoints

Align API endpoints with resources and use appropriate HTTP verbs (GET, POST, PUT, DELETE) for CRUD (Create, Read, Update, Delete) operations. These verbs are fundamental to how client and servers communicate.

✍️ 2. Versioning

Implement API versioning to manage changes and avoid breaking existing integrations. Consider using URL segments, headers, or media types for versioning.

  • Versioning via URLs

  • Versioning via Headers

  • Versioning via QueryStrings

  • Versioning via URLs

✍️ 3. Meaningful Responses

Use appropriate HTTP status codes to communicate the outcome of API requests (2xx for success, 4xx for client errors, 5xx for server errors).

✍️ 4. Error Handling

Design a robust error handling mechanism to provide informative error messages and avoid exposing sensitive information. HTTP Status Code:

  • 2xx Success

  • 3xx Redirection

  • 4xx Client Errors

  • 5xx Server Errors

✍️ 5. Data Validation

Validate user input to ensure data integrity and prevent security vulnerabilities. Consider using libraries like FluentValidation or data annotations.

✍️ 6. Security

Implement security measures like authentication and authorization to protect your API from unauthorized access.

✍️ 7. Pagination

Allow clients to request data in smaller chunks Pagination is a valuable technique for enhancing both the user experience and developer efficiency when dealing with large datasets in web applications and APIs.

✍️ 8. Filtering

Filtering, in the context of data access and manipulation, refers to the process of selecting a subset of data based on specific criteria.

✍️ 9. Caching

Implement caching mechanisms to improve API performance and reduce server load by storing frequently accessed data in memory.

✍️ 10. Documentation

Provide comprehensive API documentation to help developers understand endpoints, request and response formats, error handling, and other important details.
