A well-designed API is a joy to work with. It's intuitive, consistent, and forgiving. Let's explore the patterns that separate good APIs from great ones.
RESTful Conventions
Follow REST conventions for resource naming and HTTP methods. Use nouns for resources, verbs for actions, and HTTP status codes meaningfully.
Versioning Strategies
Whether you choose URL versioning, header versioning, or content negotiation, be consistent. Your API consumers should never be surprised by breaking changes.
Error Handling
Return meaningful error messages with appropriate status codes. Include error codes, human-readable messages, and links to documentation where relevant.
Pagination and Filtering
Support cursor-based pagination for large datasets. Provide filtering, sorting, and field selection to let clients request exactly the data they need.
