API / Swagger Interview questions
What are tags used for in Swagger?
Tags let you group related operations together for organizational purposes in the rendered documentation, so instead of Swagger UI showing one long, flat list of every endpoint in the API, operations are clustered under headings like "Users," "Orders," or "Payments."
paths: /users: get: tags: [Users] summary: List users /orders: get: tags: [Orders] summary: List orders
Tags are purely organizational metadata — they have no effect on the API's actual runtime behavior, routing, or validation — but for any API with more than a handful of endpoints, well-chosen tags are often the difference between documentation that's easy to navigate and one that's an overwhelming, undifferentiated wall of endpoints.
A top-level tags array can also be defined with descriptions for each tag name, letting the rendered documentation show a short explanation of what each group covers before listing its operations, which is especially useful for onboarding new API consumers unfamiliar with the domain.
