How do you add query parameters in Postman?

Method 1: Using the Params Tab (Recommended)

1. ✓Enter your base URL: https://reqres.in/api/users
2. ✓Click the Params tab below the URL bar
3. ✓Add key-value pairs:

   Key	Value
   page	2
   per_page	5

4. ✓Postman automatically appends them to the URL:
   CODE

   Copy

   https://reqres.in/api/users?page=2&per_page=5
   

5. ✓Click Send

Method 2: Type Directly in URL

You can also type query params directly in the URL:

https://reqres.in/api/users?page=2&per_page=5

Postman will parse and display them in the Params tab automatically.

Method 3: Using Environment Variables

https://reqres.in/api/users?page={{pageNumber}}

Set pageNumber as an environment variable with value 2.

Enabling/Disabling Parameters

Each param has a checkbox — uncheck it to temporarily disable without deleting:

☑ page      2
☐ per_page  5    ← disabled, not sent

Example Test After Adding Params

pm.test("Page number is 2", function () {
    const jsonData = pm.response.json();
    pm.expect(jsonData.page).to.eql(2);
});

Tips

• ✓Use Bulk Edit mode to paste many params at once
• ✓Query params with special characters are automatically URL-encoded by Postman
• ✓Params can be linked to collection or environment variables for dynamic testing
