Have you designed APIs and how often do you do this at work?

Yes, I have participated in API design. This usually occurs during the requirements gathering and architectural planning stages. In my work, I create API specifications, describe endpoints, methods, data formats, and usage scenarios. The frequency depends on the project — in some cases, API design is a regular task, especially when developing new services or integrations.

Example: when designing a REST API, I define resources, HTTP methods (GET, POST, PUT, DELETE), request and response structures, and status codes for different situations.
