What is API design?

API design is the process of creating application programming interfaces (APIs) that allow different software applications to communicate with each other. Good API design focuses on usability, consistency, and scalability, making it easier for developers to integrate and use the API. This involves defining endpoints, data formats, methods, and error handling strategies to ensure clear and reliable interactions between systems. Effective API design also takes into account security, versioning, and documentation to support long-term maintenance and adoption.
