Mini Project
Build Your First Postman Collection
Create a complete Postman collection called 'Public API Explorer' that tests three different public APIs: (1) JSONPlaceholder (jsonplaceholder.typicode.com) — add GET requests for users, posts, and comments organized in separate folders. (2) Open Library API (openlibrary.org/api) — search for books by subject. (3) REST Countries API (restcountries.com/v3.1) — fetch country data and filter by region. For each request, verify the status code is 200 using a basic test script. Export the collection as a JSON file.
