QA Note
What I Validate in API CRUD Flows
In Postman I validate authentication, chained requests, CRUD consistency, response schema, and data state after each action.
When I test API CRUD flows, I think in scenarios, not isolated requests. The result of one request often becomes a precondition for the next one.
- Authentication and authorization before protected actions
- Correct request body, status code, and response schema
- Use of collection or environment variables for dependent requests
- Entity relationships and data integrity after update or delete
- Negative cases for invalid data, missing permissions, and broken state transitions
This approach helps reveal bugs that are not visible in one-step API checks.
