A workspace is your home base in Postman — collections, requests, and variables all belong to one.

1. Open the Postman desktop app. If you don't have it yet, download Postman and sign in — if you're already signed in, you're good to go.
2. Click Workspaces in the top navigation → Create.
3. In Workspace name, enter [Your name] - World Explorer (e.g. Alex - World Explorer).
4. Under Select workspace type, choose Internal.
5. Under Who can access, choose Only you and invited people.
6. Select Blank workspace.
7. Click Create Workspace.

A collection groups related requests together — like a folder for your country lookups.

1. Confirm you're in your new workspace (check the name in the top-left).
2. In the left sidebar, click + → Collection.
3. Name it Country Dossier and save.

A request is a single call to an API. GET means you're asking the server for data; the URL tells it what to return. This is your first API call — don't worry about the JSON yet, just look for a green 200 OK.

1. In the left sidebar under Country Dossier, click Add request.
2. Name the request Get Country.
3. Leave the method as GET and paste this URL into the address bar:

https://liftoff-101.mock.postman.postman.dev/countries

4. Click Save (Ctrl/Cmd+S) — choose Country Dossier as the destination if prompted.
5. Click Send. You should get 200 OK — that means it worked. The JSON below is the response; you'll use it in later steps.

Query params filter what the API returns — like adding ?name=Bangladesh to narrow the list down to one country.

1. Open Get Country from your collection.
2. Click the Params tab (directly below the URL bar).
3. In the Query Params table, add a row:

4. Make sure the checkbox next to name is checked — that enables the parameter.
5. Your URL should now end with ?name=Bangladesh (or wherever you're headed). Click Send again — the response should show only your country, not the full list.
