Rubix StudiosRubix StudiosAPI design is the process of planning and structuring an application programming interface so that it is consistent, reliable, and easy for developers to use. A well-designed API defines how different software components interact, ensuring data and functionality can be accessed securely and efficiently.
Good API design focuses on usability, predictability, and scalability. It defines endpoints, methods, authentication, error handling, and documentation in a way that simplifies integration for developers and supports long-term system growth.
Advanced
API design involves architectural choices such as REST, GraphQL, or gRPC, depending on performance and flexibility needs. It also includes versioning strategies, rate limiting, caching, and pagination for handling large-scale usage.
Consistency in naming conventions, response formats, and error codes is essential. Advanced API design prioritises security through encryption, authentication (OAuth 2.0, JWT), and authorisation policies. Tools such as the OpenAPI Specification (OAS) or Postman collections are widely used to standardise, document, and test APIs, ensuring long-term scalability and reliability.

Example
A payment company designs a REST API with clear endpoints, consistent JSON responses, and strong authentication. Developers easily integrate payment processing into e-commerce platforms, increasing adoption. The company tracks response times and uptime, maintaining reliability and trust with partners.
